Answer:
a. 9 containers; $99
b. 4 containers; $76
c. $23
Explanation:
Gorilla glue comes in two sizes: an 8-ounce container for $11 and an 18-ounce container for $19.
a. How many of the smaller containers would you need in order to get 72 ounces of glue? How much would this cost?
72/8 = 9
You need 9 small containers.
9 × $11 = $99
It would cost $99.
b. How many of the larger containers would you need in order to get 72 ounces? How much would this cost?
72/18 = 4
You need 4 containers.
4 × $19 = $76
It would cost $76
c. How much do you save by purchasing 72 ounces in the larger-sized container instead of in the smaller-sized container?
$99 - $76 = $23
You would save $23.
