Two mechanics worked on a car. The first mechanic worked for 10 hours and the second mechanic worked for 15 hours. Together they charged $2500. What was the rate charged per hour by each mechanic if the sum of the two rates was $195 per hour?

Answer 1

10 x + 15 y = 2500
y = 195-x

10 x + 15(195-x) = 2500

10 x + 2925 - 15 x = 2500

5 x = 425

x = 85

y = 195-x = 110
