Answer:
Explanation:
Since we know that one bag of grapes = $3.20, we can divide $12 by $3.20 to get how many bags of grapes you can buy.
12/3.2=3.75.
In the exact amount, you can buy 3.75 bags of grapes. Now you can't buy .75 of a bag. Rounding it, you would have approximiatly bought 4 bags. Reality, you would have bought 3 bags.
