Ashley is having a Back-to-School party on Saturday. She has invited 14 friends to the party. Ashley’s mom wants to serve pizza to all the guests. One pizza contains 8 slices. If Ashley wants each of her guests and herself to have 3 pieces, how many pizzas will her mom need to order? Do we use the quotient, the next whole number, or the remainder?
To find out how many pizzas Ashley's mom needs to order, we need to calculate the total number of pizza slices needed first.
Ashley has invited 14 friends, and she wants each of them to have 3 pizza slices. So, the number of slices needed for the guests is 14 friends × 3 slices = 42 slices.
Ashley also wants to have 3 slices for herself. So we need to add 3 more slices to the total.
Therefore, the total number of pizza slices needed is 42 slices + 3 slices = 45 slices.
Now, let's calculate how many pizzas are required to get 45 slices. Since one pizza contains 8 slices, we need to divide the total number of slices needed (45) by the number of slices in each pizza (8):
45 slices ÷ 8 slices = 5.625
We use decimal numbers because dividing 45 by 8 does not give us a whole number.
So, Ashley's mom needs to order 5.625 pizzas. However, pizzas cannot be divided into decimal parts, so we cannot order a fraction of a pizza.
In this case, we have to round up to the next whole number. This ensures that there are enough pizza slices for everyone.
Therefore, Ashley's mom needs to order 6 pizzas.
To summarize, Ashley's mom needs to order 6 pizzas for the Back-to-School party.
