Question

We were ordering pizza for eight students. Each student should have at least two slices. Each pizza is cut into five slices.What is the minimum number of pizzas we should order(we can only order whole pizza)?

Answer 1

Answer:

The minimum number of pizzas we should order is 4.

Step-by-step explanation:

We have:

Eight students.

Each student should have at least two slices.

Each pizza has five slices.

Minimum number of slices:

8 students, each with at least 2 slices. 8*2 = 16.

So the minimum number of slices is 16.

Each pizza is cut into five slices.

So one pizza has ive slices, how many pizzas for 16 slices.

1 pizza - 5 slices

x pizza - 16 slices

5x = 16

x = 16/5

x = 3.2

We can only order whole pizza. If we round down, some student will have less than two slices. So we round up.

The minimum number of pizzas we should order is 4.

Answer 2

Answer:

4 pizzas

Step-by-step explanation:

According to the question, Pizzas were ordered for eight students.

Each students should have at least two slices and each pizza should be cut into five slices.

We are now told to find out the number of pizzas that should be ordered.

Let's now find a solution for this question.

If each student is expected to get at least two slices of the pizzas,then eight students are going to 16 slices of whatever number of pizzas numbered.

Now to find out the minimum number of pizzas ordered, we have to use the information we derived from the number of slices all eight students received which is 16.

And if each pizza is cut into five slices, then we need to order 4 pizzas so as to have 20 slices and each student getting atleast 2 slices from them.
