Question

Rachel bought 12 rolls of packing tape and paid a total of $33.60. Kevin also bought rolls of packing tape. The table shows the total amount he is paid for different numbers of packing tape.How do the unit rates compare?Rachel's unit rate is_____ than Kevin's because______ is greater than_____

Answer 1

To compare the unit rates of Rachel and Kevin, divide the total amount spent by the number of rolls. Rachel's unit rate is $2.80 per roll. However, we don't have enough information to compare Kevin's unit rates.

Step-by-step explanation:

To compare the unit rates, we need to divide the total amount spent by the number of rolls of packing tape. Let's calculate the unit rates for Rachel and Kevin:

Rachel: Unit rate = Total amount spent / Number of rolls = $33.60 / 12 = $2.80 per roll

Kevin: Unit rate = Total amount spent / Number of rolls

From the given table, we can see that for different numbers of packing tape, the total amounts paid by Kevin vary:

1. Total: $56.75 - Unit rate = $56.75 / Number of rolls
2. Total: $43.25 - Unit rate = $43.25 / Number of rolls
3. Total: $65.00 - Unit rate = $65.00 / Number of rolls
4. ...
5. Total: $678.25 - Unit rate = $678.25 / Number of rolls

Based on the given information, we cannot determine how Kevin's unit rates compare to Rachel's unit rate because we don't know the number of rolls Kevin bought and the corresponding total amount spent.
