Carla brought $240 to spend on gifts for her family she found a identical statues at the gift shop she had $72 leftover. how much did each statue cost?

Each one cost $21.

$240-$72=$168

$168/8=$21

original-statues=amount left

original=240

amount left=72

statues=cost per statue times cost per statue=c times 8=8c (if we use c as the cost per statue)

240-8c=72

minus 240 from both sides

-8c=-168

divide both sides by - 8

c=21

each statue cost $21
