Question

Brand A milks costs 5.28 for 2 gallons. brand B milk costs 10.40 for 4 gallons. which is the better deal per gallon and by how much?

Answer 1

To determine the price per gallon we need to divide the cost by the number of gallons.

For Brans A we have:

`C_A=\frac{5.28\text{ dollar}}{2\text{ gallon}}=2.64\text{ dollar/gallon}`

For Brand B:

`C_B=\frac{10.4\text{ dollar}}{4\text{ gallon}}=2.6\text{ dollar/gallon}`

The better price is for Brand B since:

`2.6<2.64`

The difference is:

`2.64-2.6=0.04`
