Question

Shelley's science class is heading to Wild Land Zoo on a field trip. The zoo offers a group rate for students that is $8 less per person than the normal cost. There are 25 students in Shelley's science class. Her teacher called ahead and found that the total cost for the class will be $400.
Which equation can Shelley use to find x, the normal cost per person?

Answer 1

25(x − 8) = 400

(Explanation: group rate is x − 8 per student, times 25 students equals total $400. Solving: 25x − 200 = 400 → 25x = 600 → x = 24.)
