DG's Plumbing and Heating charges $50 plus $65 per hour for emergency service. Bill remembers being billed just over $250 for an emergency call. How long to the nearest hour was the plumber at Bill's house?

Question

250 =  (? x 50) + 65

subtract 65 from both sides and then divide both sides by 50

(250 - 65) / 50 = ?

? = 3.7   nearest hour would be 4

Let be the number of hours $$50 + 65h >250$$$$65h>200$$$$h>3.07$$$$h \approx3$$
