Problema Solution
Jim's Brakes charges $25 for parts and $55 per hour to fix the brakes on a car. Myron's Auto charges $40 for parts and $30 per hour to do the same job. What length of job in hours would have the same cost at both shops?
Answer provided by our tutors
let 'x' represent the length if hours
25 + 55x = 40 + 30x
by solving we find:
x = 0.6 hr
x = 0.6*60 min
x = 36 min
