Answer 1

D

Books Cost

10

$122.50

11

$134.75

12

$147

Explanation:

The table format is all messed up but I was able to figure out the numbers.

Since 10 books cost $122.50, each book must cost $122.50/10 = $12.25

For 1 book => 10 x $12.25 = $122.50

For 11 books => 11 x $12.25 = $134.75

For 12 books => 12 x $12.25 = $147

Answer choice is D which perfectly fits the numbers
