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
