Alisiya [41]

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.
