Question

Question #5 - Solve the equation.
SpongeBob and Patrick went to a party at the Pineapple House. They each got a ticket for the Roller Coaster. SpongeBob got a Krabby Patty, and Patrick got a Krusty Krab Pizza. SpongeBob had a certificate for $7 off the cost. Patrick paid the rest, which came to $15. Each Roller Coaster ticket was $3, and a Krabby Patty was $5. What was the cost for Krusty Krab Pizza?

Answer 1

Let's denote the cost of the Krusty Krab Pizza as 'x'.
The cost of SpongeBob's ticket for the Roller Coaster is $3, and he also had a $7 discount, so SpongeBob paid 3 - 7 = -$4 for the ticket and the Krabby Patty.
The total cost that Patrick paid for the ticket and the pizza was $15, so we can set up the equation:
x + 3 = 15 - 4
x + 3 = 11
Subtracting 3 from both sides of the equation, we get:
x = 11 - 3
x = 8
Therefore, the cost of the Krusty Krab Pizza was $8.
