Question

The table below shows the cost of comic books.

Number of comic books, 3, 4, 7, 10, Total cost, in dollars, 3.75, 5, 8.75, 12.50.

Based on the information in the table, which is the best prediction of the cost of 12 comic books?



$12

$9.60

$15

$16.25

Answer 1

15 because in the table 10=12.50 so to find how much 1 is you have to move the decimal one place to the left (1.25). Then you have to do 1.25x12 which gives you 15. Hope this helps!
