What’s The Deal? Remember- to find the unit rate, you must compare the price using one as the denominator.

1 roll for $.99 Everyday Low Price Soakers Sop-A-Lot 9 for $ for $7.76 Sale Unit rate is very useful to compare costs of the same item in different quantities. Because the cost cannot be compared by the packaged amount, use the unit rate of each to do a comparison. Compare these products:

1 roll for $.99 Everyday Low Price 9 for $ for $7.76 Sal e A B C # of Rolls Total Cost Divide by Cost per roll Deal A B C Use Whiteboards to fill in the table. You may use a calculator.

1 roll for $.99 Everyday Low Price 9 for $ for $7.76 Sal e A B C # of Rolls Total Cost Divide by Cost per roll Deal A B C $0.99 $0.97 $1.16 BEST!

Which would be the best deal? A5 candy bars for $6.25 B8 candy bars for $7.28 C10 candy bars for $ 9.70 D12 candy bars for $11.04 Use whiteboard to solve. Find the unit rate for each “bargain.”

Answer: A$6.25 ÷ 5 = $1.25 per candy bar B$7.28 ÷ 8 = $0.91 per candy bar C $9.70 ÷ 10 = $0.97 per candy bar D$11.40 ÷ 12 = $0.95 per candy bar
