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 $ 1350. What was the rate charged per hour by each mechanic if the sum of the two rates was $175 per hour? Note that the ALEKS graphing calculator can be used to make computations easier. First mechanic: s per hour X 5 ? Second mechanic: s per hour
