Hello!

There are 12 inches in a foot.

Kelly buys two shelves that measure 7 feet altogether, and the cost of each foot is $1.25.

Multiply the number of feet by the cost per foot.

7 × 1.25 = 8.75

Add this to the cost of the rest of her items.

90 + 8.75 = 98.75

Finally, subtract this from the $100 Kelly will use to pay.

100 - 98.75 = 1.25

ANSWER: Kelly will receive $1.25 change after her payment.
