Question

At the Norwich Elementary School “Meet the Teachers” Breakfast, 48 parents ate a total of 90 pancakes. This rate will be used to predict the amount of food needed at next week’s middle school breakfast. If 144 parents show up next week, how many pancakes will be eaten?

Answer 1

Answer:

The parents will eat 270 pancakes.

Step-by-step explanation:

We can use proportions to solve:

48 parents               144 parents

-----------------    = ----------------------

90 pancakes                x pancakes

Using  cross products:

48 * x = 90 * 144

48x = 12960

Divide each side by 48

48x/48 = 12960/48

x = 270

The parents will eat 270 pancakes.
