Charles the Chimpanzee shopped at the Banana Peel. Bananas were on sale at 3 pounds for a dollar. Each banana weighed 4 ounces. How many bananas could Marlo buy for $7.50? (16 ounces = 1 pound)

To solve this problem, we need to convert the given information into a format that allows us to calculate the number of bananas Marlo could buy for $7.50.

First, let's convert the sale price of bananas into dollars per ounce. We know that bananas are on sale at 3 pounds for a dollar. Since there are 16 ounces in a pound, the price per ounce would be (1 dollar / 3 pounds) * (1 pound / 16 ounces) = 1/48 dollars per ounce.

Now, let's determine how many ounces of bananas Marlo can buy with $7.50. We can do this by multiplying $7.50 by the price per ounce: $7.50 * (48/1) ounces/dollar = 360 ounces.

Next, we need to calculate how many bananas can be bought with 360 ounces. Since each banana weighs 4 ounces, we divide 360 ounces by 4 ounces per banana: 360 ounces / 4 ounces per banana = 90 bananas.

Therefore, Marlo could buy 90 bananas for $7.50 at the Banana Peel.
