Question 1062590: Two mechanics worked on a car. The first mechanic worked for
10
hours, and the second mechanic worked for
15
hours. Together they charged a total of
$
2175
. What was the rate charged per hour by each mechanic if the sum of the two rates was
$
160
per hour?
Can you show me what Mechanic A Charged per hour
and what mechanic B charged per hour.
Thank you,
You can put this solution on YOUR website! mechanic a makes x dollars per hour
mechanic b makes y dollars per hour.
10x+15y=2175
x+y=160; multiply this by -10 and add to the first to eliminate x
-10x-10y=-1600
5y=575
y=$115 @ 15 hours=$1725
x=$45 @ 10 hours=$450
They add to $2175.
