Unit Rates and Cost Calculations

The video tutorial introduces the concept of unit rates, explaining that a unit rate is a ratio that compares a quantity to one unit of another quantity. The teacher provides three examples: calculating the number of deer per square mile, miles per gallon, and cost per ounce. Each example involves setting up a ratio and dividing to find the unit rate, demonstrating the process of finding equivalent ratios through division.

What does the term 'unit rate' refer to?

• A rate calculated for a single unit

• A rate calculated for multiple units

• A rate that is always increasing

• A rate that is always decreasing
