Can you solve this? The subject is about solving equations using addition and subtraction.

Answer:
$5.25
Step-by-step explanation:
add all the prices up and subtract it from $15
bumper cars : 1.75
giant slide : 1.75 - .50 = 1.25
ferris wheel : 1.25 + 1.50 = 2.75
roller coaster : 2.75 + 1.25 = 4.00
1.75 + 1.25 + 2.75 + 4.00 = 9.75
15 - 9.75 = 5.25
