Question

At a pizza eating competition, Sean ate three more than twice as many slices as the runner-up. If Sean ate 11 slices, then how many slices did the runner-up eat?

A. 2 slices
B. 3 slices
C. 4 slices
D. 5 slices

Answer 1

The runner-up ate 4 slices.

Step-by-step explanation:

To determine how many slices the runner-up ate, we can first set up an equation using the information given. Let's call the number of slices the runner-up ate 'x'. According to the problem, Sean ate three more than twice as many slices as the runner-up, so we can write an equation: 2x + 3 = 11. We can solve this equation by subtracting 3 from both sides: 2x = 8. Then, we divide both sides by 2 to find that x = 4. Therefore, the runner-up ate 4 slices.
