Question

Adeline buys 8 packs of Fun Gum. Each pack has 7 pieces of gum. Marisol buys Juicy Gum. Each Juicy Gum pack has 9 pieces of gum.Adeline has 11 more pieces of gum than Marisol. How many packs of gum did Marisol buy?

Answer 1

The number of packs is 5.

Explanation:

Let the number of juicy packs of gum bought by Marisol be represented by n.

Adeline bought 8 packs of Fun gum with each pack containing 7 pieces of gum.

Total number of gums has Adeline = 8 x 7

= 56

Total pieces of gum has Marisol = n x 9

= 9n

Given that Adeline has 11 more pieces of gum than Marisol, thus;

56 = 9n + 11

56 - 11 = 9n

45 = 9n

n =
`(45)/(9)`

n = 5

The number packs of juicy gum bought by Adeline is 5 and total pieces of his gum is 45.
