Math problem quantity with price

Question

How do I calculate if 1 gal of gas costs 3.49 how much would it cost to buy 1.86 gallons?

Answer 1

Hi Marcie! In this case, we know 1 gallon of gas costs $3.49. If we are to find the cost of 1.86 gallons, we would simply need to multiply 1 gallon by 1.86 and therefore $3.49 by 1.86 to get $6.49. Hope this helps.
