Question

Two mechanics worked on a car. The first mechanic worked for 15 hours, and the second mechanic worked for 5 hours. Together they charged a total of $1675. What was the rate charged per hour by each mechanic if the sum of the two rates was $185 per hour?

Answer 1

Lets start by writing out the two equations

Answer 2

I'm having trouble writing these two

Answer 3

Ok. I will start by giving each mechanic a variable. The first mechanic will have the variable m and the second mechanic will have the variable n. The first equation has to do with the rate at which they are paid. So the equation would be 15m+5n=1675. Then they tell you what the sum of the hours are so m+n=185. Does this make sense?

Answer 4

yes.

Answer 5

Then I solved and I got 75 for the first mechanic and 110 for the second
