Question

Wanda is going to the water slides and needs to figure out which deal is better. She can pay

$32 to go on the water slides as much as she wants, or she can pay $18 to get in, plus an
additional $2 per trip down the water slides. If Wanda goes on a certain number of trips down
the water slides, the two options are equivalent in terms of cost. What is the cost? How many
trips is that?

Answer 1

Answer: The cost for the total trips is $14. The amount of trips that Wanda can make is a maximum of 7 to equal the amount.

Explanation:

First, make the amount of trips, x

Step 1. $32 = $18 + $2x

Step 2. ($32 - $18) = ($18 - $18) + $2x

Step 3. $14 = $2x

Step 4. $14 / $2 = $2x / $2

Step 5. $7 = x

Step 6. $32 = $18 + ($2 * 7)

Step 7. $32 = $18 + $14

Step 8. Check for the equation. $32 = $32
