Answer 1

Alright, so they are asking to compare the two prices. First you need to know how much for one unit. Do you know how to find out how much each unit costs for the rolls Rachel bought?

Answer 2

no

Answer 3

?????

Answer 4

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?
