Final answer:
To calculate the unit rates for cans of baked beans, theater tickets, and tire installation, divide the total cost or time by the number of items or activities involved. The unit rate for beans is $0.80 per can, for tickets $13.95 per ticket, and for tire installation, it's 7.5 minutes per tire.
Step-by-step explanation:
To find the unit rates, we divide the total cost by the number of items to determine the cost per single item or the cost per single unit of measure. This concept is similar to determining the cost of apples, bananas, grapes, and raspberries in our example prices from 2001. Let's calculate the unit rates for each of the scenarios provided:
- Cans of baked beans: $2.40 for 3 cans. To find the unit rate, divide $2.40 by 3, which gives us $0.80 per can.
- Crystal's theater tickets: $83.70 for 6 tickets. The unit rate is found by dividing $83.70 by 6, resulting in a cost of $13.95 per ticket.
- Garrett's tire installation: 0.5 hour to install 4 new tires. Here, we divide 0.5 hours by 4 to get the unit rate of 0.125 hours, or 7.5 minutes, per tire.
Understanding unit rates is important, as they allow consumers to compare the cost or value of items and services efficiently, just like Alphonso's budget problem where he has to allocate his spending wisely between bus tickets and burgers.
