Question

11. The table below shows the cost of comic books. Number of Comic Books Total Cost (dollars) 3 3.75 5 7 8.75 10 12.50 Based on the information in the table, which is the best prediction of the cost of 12 comic books?​

Answer 1

$15

Explanation:

The unit rate or how much a comic book costs = total cost ÷ number of comic books

Using any given pair, let's use the first row (3, 3.75):

Unit rate =
`(3.75)/(3) = 1.25`

This means a comic book cost $1.25.

Therefore, 12 comic books would cost:

12 × 1.25 = $15
