Answer:
$12.50
Step-by-step explanation:
The cost of 5 bags will be 5/3 times the cost of 3 bags:
5-bag cost = (5/3)($750) = $12.50
Marco would spend $12.50 on 5 bags of cat food.
_____
If you like, you can find the "unit rate" -- the cost of one bag of cat food:
$7.50 / (3 bags) = $2.50 /bag
Then, multiply that rate by 5 bags:
(5 bags)($2.50/bag) = $12.50
Note that we have multiplied by 5 and divided by 3, the same as if we had multiplied by 5/3.
