A plumber charges $65 for a service call, plus $32 per hour of service. If he charged Mr. Jackson $257, how many hours did we work? Write an equation that represents the situation. Then, find how many hours he worked.

Respuesta :

257= 32x+65 he worked 6 hours
Equation: 65+32x=257
(65-65)+32x=257-65
32x=192
32x/32=192/32
X=6
He worked 6 hours
