Question

Sarah made a certain number of bracelets for a craft show. Maria made 7 more than Sarah. Julie made 3 times as many as Maria. Which expression represents the total number of bracelets Julie made if Sarah made s bracelets?

Answer 1

Total no of bracelets = 5s+28

Explanation:

Let Sarah made s bracelets.

Maria made 7 more than Sarah i.e. 7+s

Julie made 3 times as many as Maria i.e. 3(7+s)

Total no of bracelets made is equal to the sum of the bracelets made by Sarah, Maria and Julie.

Total = s+ 7 + s + 3(7+s)

= 2s+7+21+3s

=2s+3s+21+7

= 5s+28

So, there are (5s+28) bracelets.
