Question

there is a group of 9 people ordering pizza if each person gets 2 slices and each pizza has 8 slices how many pizzas should they order ?

Answer 1

Total People = 9

Each person gets 2 slices, so 9 person will get:

9 * 2 = 18 slices

We would need 18 slices altogether.

Since each pizza has 8 slices, we can write:

1 pizza = 8 slices

2 pizza = 8 + 8 = 16 slices

3 pizza = 8 + 8 + 8 = 24 slices

Taking 2 pizza means we will have 16 slices, but we need atleast 18. So that is 2 short. We would need to order another pizza.

So we would need 2 + 1 =
