Break Even Analysis for Small Business 1) Jesse wants to start a business making and selling skateboards. She will charge $75 for each one. Her cost will be $30 per skateboard for materials. She must pay $500 per month rent (which includes utilities) so that she has a place to make and sell the skateboards. a) Write a rule for her revenue (money coming in). b) Write a rule for her cost.
Answers
Answer:
a) r(b) = 75b
b) c(b) = 30b +500
Step-by-step explanation:
Revenue is the product of the selling price per unit and the number of units. The cost will be the sum of fixed (overhead) cost and production cost per unit multiplied by the number of units produced.
__
Let b represent the number of skateboards Jesse produces in a month.
a)Jesse receives $75 for each skateboard sold. Her revenue from selling 'b' skateboards is ...
r(b) = 75b
__
b)It costs Jesse $30 for each skateboard produced, and $500 for overhead. Her total cost is ...
c(b) = 30b +500
_____
Additional comment
In order to break even, Jesse's revenue must equal her cost:
75b = 30b +500
45b = 500
b = 11 1/9
Jesse must produce and sell 12 skateboards each month to cover her costs. (In a real business, there are additional considerations related to inventory, shrinkage, returns, discounts, and other things that may increase cost or reduce revenue.) After covering costs, each additional skateboard sold will give Jesse a profit of $45.
4. A punch bowl holds 80 oz of punch, that is enough for exactly 16 servings.
Hillary says that there are 20oz of punch for every 5 servings. Is Hillary correct?
Answers
Answer:
No, Hillary is incorrect. There's 20oz of punch for every 4 servings.
Step-by-step explanation:
80oz / 20oz = 4
16 servings / 4 = 4 servings
So, instead of there being 20oz of punch for every 5 servings, there would be 20oz of punch for every 4 servings.

Answer: C. [tex]f(n) = -4(-3)^{n-1}[/tex]
Step-by-step explanation: The formula for a geometric sequence is [tex]ar^{n-1}[/tex], where a = first term in the sequence
r = common ratio
n = position of term
Here they already told us a = -4, so we have to figure out r. We can see that in the sequence -4, 12, -36, 108... the terms are being multiplied by -3, which is why the negative and positive terms alternate.
Therefore, the formula is: [tex]f(n) = -4(-3)^{n-1}[/tex]
You can try inserting n to check it.
[tex]f(1) = -4(-3)^{1-1} = -4\\f(2) = -4(-3)^{2-1} = 12\\f(3) = -4(-3)^{3-1} = -36\\f(4) = -4(-3)^{4-1} = 108[/tex]
Option C
Let's verify
f(1)=-4(-3)^0=-4f(2)=-4(-3)^1=12f(3)=-4(-3)^2=-36Hence verified

Shannon needs 20g of 80% gold to make a pendant. She has some 85% gold and some 70% gold. How much of each should she use of each alloy, use two linear equations to solve
Answers
Answer:
85%: 13 1/3 grams70%: 6 2/3 gramsStep-by-step explanation:
Two equations can be written to describe the desired relationships. One can describe the total quantity of gold alloy needed. The other can describe the amount of gold in the combination of alloys.
Let x and y represent the quantities in grams of 85% and 70% gold alloy needed, respectively.
x + y = 20 . . . . . . Shannon needs a total of 20 grams
0.85x +0.70y = 0.80(20) . . . . . the amount of gold in the mix of alloys
__
These equations are often nicely solved by substitution. Substituting for y, we have ...
0.85x +0.70(20 -x) = 0.80(20)
0.15x = 0.10(20) . . . . . . . eliminate parentheses, subtract 0.70(20)
x = 40/3 = 13 1/3 . . . . . divide by 0.15
y = 20 -13 1/3 = 6 2/3
Shannon should use 13 1/3 grams of 85% alloy and 6 2/3 grams of 70% alloy.
On the speed-time graph, the Y-axis should be labeled as

Matthew bought 16 gallons of gas for $4.25 per gallon. How much did he spend? Show your work.
Answers
Answer:
$68.00
Step-by-step explanation:
16 x 425 = 6800
Just move the decimal 2 places to the left to get 68
Matthew spends $68 on gas as the rate of gas is $4.25 per gallon.
What is per unit?Per unit is a technique of expressing a quantity's value in terms of a base or reference quantity. Each system variable or quantity in a per-unit system is normalized in relation to its own base value.
Given Matthew bought 16 gallons of gas for $4.25 per gallon.
Since the price per gallon = 4.25
The price of the gas for 16 gallons = 4.25 * 16
The price of the gas for 16 gallons = 68.00
Therefore, Due to the $4.25 per gallon price, Matthew spends $68 on gas.

Darren wants to estimate the mean age in a population of trees. He'll sample nnn trees and build a 90\%90%90, percent confidence interval for the mean age. He doesn't want the margin of error to exceed 333 years. Preliminary data suggests that the standard deviation for the ages of trees in this population is \sigma=16σ=16sigma, equals, 16 years. Which of these is the smallest approximate sample size required to obtain the desired margin of error?
Answers
Using the z-distribution, as we have the standard deviation for the population, it is found that the smallest sample size required to obtain the desired margin of error is of 77.
What is a z-distribution confidence interval?The confidence interval is:
[tex]\overline{x} \pm z\frac{\sigma}{\sqrt{n}}[/tex]
In which:
[tex]\overline{x}[/tex] is the sample mean.z is the critical value.n is the sample size.[tex]\sigma[/tex] is the standard deviation for the population.The margin of error is given by:
[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]
In this problem, we have that the parameters are given as follows:
[tex]M = 3, z = 1.645, \sigma = 16[/tex].
Hence, solving for n, we find the sample size.
[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]
[tex]3 = 1.645\frac{16}{\sqrt{n}}[/tex]
[tex]3\sqrt{n} = 1.645 \times 16[/tex]
[tex]\sqrt{n} = \frac{1.645 \times 16}{3}[/tex]
[tex](\sqrt{n})^2 = \left(\frac{1.645 \times 16}{3}\right)^2[/tex]
[tex]n = 76.97[/tex]
Rounding up, the smallest sample size required to obtain the desired margin of error is of 77.
