Given:

Arnies car used 100 cups of gasoline during a drive. He paid $3.12 per gallon for gas.

Determine how much did the gas cost.

Solution:

In order to determine the gas cost, we simply needed to convert cups to gallons first. We can do this by simply doing the general conversion method.

1 gallons = 16 cups

= (100 cups )(1 gallons/ 16 cups)

= 100 gallons/ 16

= 6.25 gallons

Multiply 6.25 by 3.12.

= (6.25 gallons)($3.12 per gallon)

= $19.5

Final answer:

= $19.5
