Question

A water park charges $5 for entry into the park and an additional $2 for each of the big waterslides. Steven spent $17 on his visit to the water park. Which equation can be used to find the number of big waterslides, x, that Steven went on?

a. 5 + 2x = 17
b. 5x + 2 = 17
c. 5x + 2x = 17
d. 5 + 2 = 17x

Answer 1

5 is a constant - you pay $5 before you go on any of the waterslides.
let the number of waterslides Steven went on = x

5 +2x =17 ($5 plus $2 per waterslide ride = 17)

Answer a is correct.
By the way, Steven went on 6 waterslide rides.
