Answer: Rachel's unit rate is less than Kevin's because 3.2 is greater than 2.8.
Step-by-step explanation:
Given: Rachel bought 12 rolls of packing tape and paid a total of $33.60.
Therefore, the unit rate of tape bought by Rachel = [tex]\frac{33.60}{12}=\$2.8[/tex]
Hence, the unit rate of tape bought by Rachel =$2.8
From the table , Kevin bought 2 rolls of packing tape and paid a total of $ 6.40.
The unit rate of tape bought by Kevin =[tex]\frac{6.40}{2}=3.2[/tex]
Hence, the unit rate of tape bought by Kevin = $3.2
Clearly, 3.2>2.8
Therefore, Rachel's unit rate is less than Kevin's because 3.2 is greater than 2.8.
