Answer 1

To know the best deal, we have to know which one gives us the least cost per gallon.

To do that we divide the price by the quantity or volume.

A) $56 for 25 gallons

`\frac{56\text{ \$}}{25\text{ gal}}=2.24\text{ \$/gal}`

B) $32.05 for 15 gallons

`\frac{32.05\text{ \$}}{15\text{ gal}}\approx2.14\text{ \$/gal}`

C) $51.29 for 23 gallons

`\frac{51.29\text{ \$}}{23\text{ gal}}=2.23\text{ \$/gal}`

D) $22.50 for 10 gallons

`\frac{22.50\text{ \$}}{10\text{ gal}}=2.25\text{ \$/gal}`

The best deal is B: $32.05 for 15 gallons, because it offers a price per gallon that is lower than the others.
