Question

Two car owners are in need of car repairs. Elise will need to pay the mechanic $1 per

minute for labor, plus $350 to cover the cost of new parts. Kayla will need to pay $200
for parts and $2 per minute for labor. Depending on how long each repair takes, the
two jobs might end up costing the same amount ?

Answer 1

yes, if the labor takes 150 minutes (or 2h 30 minutes)

Explanation:

m + 350 = 2m + 200

2m - m = 350 - 200

m = 150
