Question

2.P.S. 89 is having an ice cream social for the graduating 8th grader.

a.
Ms. Gallo has to order the ice cream. She decided to order 21 cartons of vanilla ice cream and 28 cartons of
chocolate ice cream. Let V to represent cost of the vanilla ice cream and C to represent the chocolate ice cream
Write an algebraic expression that represents the total cost of buying the ice cream.
b.
Write an equivalent expression for your answer in part (a).
C.
Explain why the expressions are equivalent.

Answer 1

21v+28c=t(total)

(21+28)x(v+c)

It would be equivalent because in “a” you are multiplying the cost of each container with how much brought and in “b” you are adding the prices to multiply it by how much ice cream she brought in total
