Ronnie charges his customers a flat fee of $25 to fix computers. Then he charges $20 for each hour that he spends fixing the computer. If Ronnie made $175 off the first customer, how many hours did he spend working?
Answers
Answer:
fhrecvregvrsgrrfdrerdggbrsdvrg
Step-by-step explanation:
Just do 175 divided by 20
Answer:
7.5
Step-by-step explanation:
Ronnie charges $25 plus $20 per hour. This means that he made the following depending on how many hours he spent on it:
Hours Dollars
0 25 = 25 + 0(20)=25
1 25+20 = 25 + 1(20)=45
2 25+20+20 = 25 +2 (20)=65
3 25+20+20+20 = 25 +3 (20)=85
4 25+20+20+20+20 = 25 +4 (20)=105
5 25+20+20+20+20+20 = 25 +5 (20)=125
n 25+n(20)=175
To find how many hours he worked for $175 we solve the equation using inverse operations:
25+n(20)=175
25-25+n(20)=175-25
n(20)=150
n= 7.5 hours

Which comparison is true? Use the number line to help.
A number line going from negative 6 to positive 6 in increments of 1.
x June < August
✔April = May
x May > July
x May = August
Step-by-step explanation: took quiz on edge 2021 made 100
The required comparison that is true is that Westin Trading's sales were below average for the five months.
What is Statistic?Statistics is a field of mathematics that deals with relations between comprehensive data.
Here,
To determine the comparison that is true, we need to find the total variance from the average for the five months and compare it to zero on the number line. We can do this by adding up the variances and dividing by the number of months:
Total variance = (-2.5) + (-2.0) + 3.1 + (-1.6) + 2.67
Total variance = -0.32
Average variance = -0.32 ÷ 5
Average variance = -0.064
Since the average variance is negative, this means that Westin Trading's sales were below the average of $6 million per month for the five months. To compare this to zero on the number line, we can see that the average variance of -0.064 is to the left of zero, which represents the average sales of $6 million per month. Therefore, the comparison that is true is that Westin Trading's sales were below average for the five months.
