no

Alright, so it is pretty simple. You take to total cost divided by how many units she bought. So that would be: \[33.60 \div 12=2.8\] So that is equal to $2.80 Now the same thing applies to the ones in the table. Total cost divided by the total units he bought: \[6.40 \div 2=3.2\]\[16 \div 5 = 3.2\]\[25.60 \div 8 = 3.2\] So each roll Kiven bought is $3.20. Do you know how to find the difference?
