Question

or
Chase and his scout troop are heading to Crazy Cascades river rafting. They plan to purchase the group package. With the package, the cost per person is $6 less than the normal cost for an individual. There are 15 scouts in Chase's troop. His troop leader called ahead and found that the total cost for the group will be $210.
Which equation can Chase use to find the normal cost, x, for an individual?

Answer 1

Let x = normal individual cost. The group price per person is x - 6, and 15 people pay that, so:

15(x - 6) = 210.

(If you solve it: x - 6 = 14, so x = $20.)
