Agrocery store sells three different quantities of sugar. a 1-pound bag costs $1.10, a 2-pound bag costs $1.98, and a 3-pound bag costs $2.64. describe how the unit cost changes as the quantity of sugar increases.

unit cost is cost of 1 unit of a product, here its cost of 1 pound of sugar.

In first case unit cost is $1.10.

In second case cost of 2 pound = $1.98, or cost of 1 pound = [1.98/2] = $0.99.

In third case cost 3 pound = $2.85, or cost of 1 pound = [2.85/3] = $0.95.

We can see that as the quantity is increasing unit cost is decreasing.
