Part 1) The number of cups of flour needed to make 4 pizzas is 26

Part 2) The number of pizzas Luigi can make with 13 cups of flour is 2

Step-by-step explanation:

we know that

Luigi uses 39 cups of flour for every 6 pizzas he makes

Let

y ----> the number of cups of flour used

x ---> the number of pizzas he makes

In this problem

The relationship between the variables x, and y, represent a proportional variation

we have the ordered pair (6,39)

so

Part 1) Find out the number of cups of flour needed to make 4 pizzas

using a proportion

Solve for y

Part 2) Find out the number of pizzas Luigi can make with 13 cups of flour

using a proportion

Solve for x

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.
