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
