Example Problems:

- You want to take snowboard lessons, and a friend of yours had a good experience taking them at Hunter Mountain. She remembers that the total cost for six lessons was $260 and that the first lesson was one and a half times the cost of each of the other five. What is the cost of each of the lessons?

1) c: cost of each of the "other five" 2) cost of 1st = 1.5c (or 3/2) 3) The cost of all = $260 4) 1.5c + 5c = 260 5) 1.5c + 5c = 260 6.5c/6.5 = 260/6.5 c = 40 1.5c = 60 <-- cost of the 1st lesson

Check your answer: 40(5) = 200 + 60 = 260. check

6) The 1st lesson costs $60 and each of the other five lessons was $40.

- A car that goes 8km/hr travels 12km. HOw many hours does it take? 1) t = how much time 2) 8/1 = 12/t cross multiply 3) 8t = 12 4) 8t/8 = 12/8 5) t = 1 hour and 30 minutes 6) check: 8/2 = 4 = 30 minutes. 8 + 4 = 12 12 =12 km. check
