An appliance repair person charges $55 per trip plus $15 per hour for her labor. The cost of fixing a stove was $92.50. Write and solve an equation to find how many hours it took to repair the stove.

Respuesta :

15x + 55

92.50 - 55 = 37.5

37.5 divided by 15 = 2.5

She worked for 2.5 hours and added the $55 charge.
