Two mechanics worked on a car. The first mechanic charged $65 per hour, and the second mechanic charged $90 per hour. The mechan
Katena32 [7]

Answer:

First mechanic worked 20 hours and second mechanic worked 5 hours

Step-by-step explanation:

Let the number of hours the first mechanic worked = a

Let the number of hours the second mechanic worked = b

Therefore, we can write 2 equations and then solve them simultaneously:

a+b=25

65a+90b=1750

Rearranging the first equation: a=25-b

and substituting into the second equation to find b:

65(25-b)+90b=1750

1625-65b+90b=1750\\
25b=125\\
b=5

Now sub b=5 into the first equation to find a

a+5=25\\
a=20

Therefore, first mechanic (a) worked 20 hours and second mechanic (b) worked 5 hours
