Question

12. Allison is buying some boxes of frozen treats: popsicles, p, ice cream bars, b, and ice cream

sandwiches, s. All three items cost $2.25 for each box. Write two equivalent expressions to
determine how much Allison will spend on all the frozen treats.

Answer 1

One possible answer is: 2.25p + 2.25b + 2.25s

Another possible answer: 2.25(p + b + s)

==========================================================

Step-by-step explanation:

• p = number of popsicles
• b = number of ice cream bars
• s = number of ice cream sandwiches

Each item costs $2.25 per box, so,

• 2.25p = cost of just the popsicles only
• 2.25b = cost of just the ice cream bars only
• 2.25s = cost of just the ice cream sandwiches only

Add up those subtotals to get the grand total

2.25p + 2.25b + 2.25s

is one possible answer

What we can do is factor out the common 2.25 using the distributive rule in reverse.

Another possible answer is: 2.25(p + b + s)
