Question

4 glue sticks cost \$7.76.
Which equation would help determine the cost of 13 glue sticks?

Answer 1

The answer is: $25.22

First, we want to find the unit price of one glue stick. To find this value, we simply divide the price by the number of glue sticks bought. We find that $7.76/4 is equal to $1.94. To find the price of 13 glue sticks, we multiple the unit price of one glue stick by the number of glue sticks we desire (in this case, 13). $1.94 • 13 equals $25.22.

Answer 2

x = $20.40

Explanation:

x = cost of 13 glue sticks

4 glue sticks cost $7.76, so to find the cost of 13 glue sticks, you would use the equation:

x = (13/4) * $7.76

or

x = $20.40
