Question

Mary is serving pizza at her party. Including her parents, there are 25 people. Each person will get two slices of pizza and a glass of juice. Each pizza is cut into eight slices. Each can of juice fills three glasses. How many pizzas are needed for the party? How many cans of juice?

Answer 1

7 pizzas and 9 cans of juice

Explanation:

The answer is 7 pizzas because if you add the 25 people plus her parents (That would be two more people) is 27. Then you have to multiply 27×2 that would equal 54. So, now you know you need 54 slices but what you is the amount of pizzas needed. The next step would be to divide 54÷8 that would equal 6.75 but you can't buy 6.75 pizzas, and you can't buy 6 pizzas because than you would leave people outside. You will need to buy 7 pizzas. It is better to have left overs than leaving people outside.

For the amount of cans would be 9 because if you add again 25 people plus her parents it would be 27. Then you multiply 27×1 that is obviously 27. The next step would be to divide 27÷3 and it would equal 9. And that is how you get your answer.
