Question

Filipe went on the roller coaster 4 times and the gravity free-fall once, for a total of $24.00. Luiza went on the roller coaster four times and the gravity free-fall twice, for a total of $30.00.

How much does one ride on the gravity free-fall cost?
A. $30.00
B. $12.00
C. $6.00
D. $8.00

Answer 1

The answer is $6 if felipe went on the roller coaster 4 times and 1 time in the free fall and it ended up being 24 you just have to subtract 30 from 24 and it gives you six. To check if this is right you just subtract 6 once from 24 and add six again two times like this

24-6=18
18+6+6= 30
