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?
+36916 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
