Question
Apples are sold in bags of four that cost 6 per bag. What is the lowest cost at which you can buy 75 apples?
Solution
To solve this problem, we need to find the most cost-effective way to buy 75 apples.
-
First, let's calculate the cost per apple for each bag. For the bag of four apples, the cost per apple is 1.25. For the bag of six apples, the cost per apple is 1.
-
Since the bag of six apples is cheaper per apple, we should buy as many of these as possible.
-
To find out how many bags of six we can buy, we divide 75 by 6. The result is 12.5. Since we can't buy half a bag, we buy 12 bags of six apples.
