Wonderland Water Park
The Coaster: $4.50
The Slide: $4.00
The Drop: $3.50

You and Three friends are going to Wonderland Water Park. Your group plans to ride each water ride twice. Prices are shown in the table above. How much change will you get back from a $100 bill?
A $96
B $4
C $24
D $12

Answer 1

1) (450x4)2=36
2) (4x4)2=32
3) (3.50x4)2=28
4) 36+32+28=96
5) 100-96=4

The answer is: B

Answer 2

you + 3 friends = 4 people
all 3 rides = $4.50 + $4.00 + $3.50 = $12.00
4 people = $12.00 * 4 = $48.00
riding slide twice = $48 * 2 = $96

change = $100 - $96 = $4

answer is B. $4

i hope this helps :)
