Showing How Your Sliding Price Scale Works

Use this resource to help you show how your sliding price scale works.

It’s important to show how your sliding price scale will work using an example.

Suppose a grocery store buys 100 pounds (lb.) of bananas at $0.30/lb. and uses the following sliding price scale:

Amount of Time on Shelf Discount Price Survey Results
0-5 days Full Price (no discount) $0.60/lb. 75% would choose
5-10 days 40% discount $0.36/lb. 70% would choose

In the first 5 days, how many pounds of bananas will be purchased by customers, according to the survey results? Show using calculations.

In the next 5 days, how many pounds of bananas will be purchased by customers, according to the survey results? Show using calculations.

After 10 days, how many pounds of bananas will be left over? How does this compare to what would happen if the grocery store didn’t have a sliding price scale?

What will be the grocery store’s profit?
