Answer:

x=$2.50, y=$4.00

Step-by-step explanation:

Let x=cost of the water slide

Let y=cost of the ferris wheel

System of equations:

3x+3y=19.50

2x+3y=17.00

Subtract the 2nd from the 1st to get:

x=2.50

Now plug into first equation to get:

3(2.50)+3y=19.50 so y=4.00

Check in 2nd equation:

2(2.50)+3(4) = 5+12 = 17
