You need to buy laundry detergent and your favorite brand comes in three different sizes. Size 1 costs $7 and is enough for 28 loads, size 2 costs $14.72 and is enough for 64 loads, and size 3 costs $24 and is enough for 100 loads.

Which size is the best deal?

size 2 will be the better deal because if you divide all the size 1,2,3 by the cost and the loads the cheapest one per load is size 2 @23 cents each load
