unit rate definition math is fun
Unit Price. The Unit Price (or unit cost) tells you the cost per liter, per kilogram, per pound, etc, of what you want to buy. Just divide the cost by the quantity: Example: 2 liters for $3.80 is $3.80/2 liters = $1.90 per liter.o the lowest Unit Price (and the best bargain) is 1.5 liters at $2.70. Of course it doesn't tell you the quality of what you are buying, but it can help you make a decision.
