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
