Question

The unit price on a 100-pound container of swimming pool chlorine is $0.06 per pound less than the unit price on a 75-pound container. If the 100-pound container costs $55.50 more that the 75-pound container, find the cost of each

Answer 1

Hi Jessica,

The hint here is to think of both containers in terms of price, let's call it P, and set them equal to each other...but the 100 lb container is $55.50 more, so turned into an equation...

100 lb (P - $.06)/lb = 75 lb (P)/lb + $55.50

Now you can solve!
