A water park has 28 water attractions: pools, game areas, and water slides. There are P pools and P +2 games areas. If 50% of the attractions are water slides, how many games areas are there?

Respuesta :

Answer:

9

Step-by-step explanation:

Let's first start by writing some equations. If we say P = Pools, G = game areas,  and W = Water slides, we have the following:

P + G + W = 28

W = 1/2 (28)

G = P + 2

We can first see that there are 14 water slides. There are 14 attractions left, which are split into the pools and game areas. We have a new equation.

P + G = 14

We know that G = P + 2, and substituting this in, we have:

P + P + 2 = 14.

2P = 12

P = 7.

There are 7 pools, and since G = P + 2, there are 9 game areas.
