What does one fourth of a can coffee cost if 4 cans costs 2.40?

Here's how to solve this:

* Find the cost of one can: Divide the total cost by the number of cans: $2.40 / 4 cans = $0.60 per can

* Calculate the cost of one-fourth of a can: Divide the cost of one can by 4: $0.60 / 4 = $0.15

Therefore, one-fourth of a can of coffee costs $0.15.
