Question

Larry bought 12 containers of pasta salad for a school picnic. Each container held the same number of ounces of salad. Students finished the pasta salad in 8 of the containers.

A.Let p equal the number of ounces of pasta salad in one container. Write an expression with two terms to represent how many ounces of pasta salad are left.


B.Simplify the expression you wrote in problem 6 to create an equivalent expression. Use the distributive property.

Answer 1

12 p - 8 p, 4p ( 3 - 2)

Explanation:

p = equal the number of ounces of pasta salad in one container

then 12 × p = 12 p in 12 containers

the students finished the pasta salad in 8 containers which equals = 8 p

the number of ounces of pasta left = 12 p - 8 p

b) using the distributive property for example a ( b + c) = ( a×b) + (a ×c)

12 p - 8 p = 4p ( 3 - 2)
