Question

Tiana is going to the water slides and needs to figure out which deal is better. She can pay $35 to go on the water slides as much as she wants, or she can pay $15 to get in, plus an additional $1 per trip down the water slides. If Tiana goes on a certain number of trips down the water slides, the two options are equivalent in terms of cost. How many trips is that?

Answer 1

Let x = number of trips

The two options cost the same when 15 + x = 35

Solve for x.

Answer 2

You will perform this as an equivalent equation.

When do you break even with this deal?

35 is the total cost without any additional fees. Cost 1: $35

Otherwise, you will pay $15 plus 1 times how many times you slide. Cost 2: $15 + 1x

Now, place these two equations equal to each other and solve for x.

$35 = $15 + 1x
