Two snow resorts offers private lessons to their customers. Big Time Ski Mountain charges $5 per hour plus $50 insurance. Powder Hills charges $30 per hour plus $10 insurance. For what number of hours is the cost of lessons the same for each resort?
We need to solve this :
5h + 50 = 30h + 10 subtract 10, 5h from both sides
40 = 25h divide both sides by 25
40 / 25 = h = 8/5 hrs = 1.6 hrs equalizes the cost
