Two mechanics worked on a car. The first mechanic worked for 10 hours, and the second mechanic worked for 5 hours. Together they charged a total of $1325. What was the rate charged per hour by each mechanic if the sum of the two rates was $170 per hour?

#1**+1 **

x = rate 1 10x = amount

170 -x = rate 2 5 (170-x) = amount

Added together = 1325

10x + 5 (170-x) = 1325

10x + 850 -5x = 1325

5x= 475

x =rate 1 = $ 95 /hr (yikes...Doctors' wages !)

rate 2 = 170-x = $ 75/hr
