Answer 1

Answer: Multiplication and Subtraction

Multiplication is used to find the amount needed for all of a certain item.
ex. 2 x 24 = 48

Subtraction is used to see how much is left over after she purchases the items
ex. 80 - 69 = 11

Answer 2

$24×2=$48
$7×3=$21
$48+$21=$69
$80-$69=$11
Multiplication and subtraction are used.
