Question

Juan ordered 20 pizzas for a party. 45% of the pizzas have 8 slices each. The remaining 55% of the pizzas have 12 slices each. Complete the model. Then complete the statements to find the total number of slices of pizza.

Answer 1

Explanation:

Model:

s = slices

x = pizzas ordered

s = .8(.45x) + .12(.55x)

Now plugin 20 for x and you will get the total number of slices.

s = .8(.45x) + .12(.55x)

s = .8(.45(20)) + .12(.55(20))

s = 204 slices

Note, we could make this model different and smaller but I chose this method because it demonstrates what is going on with the word problem
