Two mechanics worked on a car. The first mechanic worked for
20
hours, and the second mechanic worked for
5
hours. Together they charged a total of
$1725
. What was the rate charged per hour by each mechanic if the sum of the two rates was
$120
per hour?
Note that the ALEKS graphing calculator can be used to make computations easier
