The price of gasoline purchased varies directly with the
number of gallons purchased. If 10 gallons of gasoline are
purchased for $28, what will the price of 15 gallons be?
Explanation: first I will be dividing 28 by 10, which will be giving me a total of 2.8 Next I will multiply 2.8 by 15 which it will be giving me a total of 42.
