The unit price on a 100-pound container of a swimming pool chlorine is $.06 per pound less than the unit price on a 75-pound container. If the 100-pound container costs $55.50 more than the 75-pound container, find the cost of each.

100 lb: $240 75 lb: $184.50

Step-by-step explanation:

Let u represent the unit price of the 100 lb container. Then u+.06 is the unit price of the 75 lb container.

The difference in prices is ...

100u - 75 (u+.06) = 55.50

25u - 4.50 = 55.50

25u = 60

u = 60/25 = 2.40

The cost of the 100 lb container is 100u = 240. The cost of the 75 lb container is $55.50 less: 240 - 55.50 = 184.50.

The 100 lb container costs $240. The 75 lb container costs $184.50.
