Question

You need 12 gallons of paint to paint the exterior of your house. At one store the paint sells for $19.95 a gallon. At a second store the same brand of paint sells for $37.98 for two gallons. Which store is less expensive?

Answer 1

(12*19.95) : (37.98*(12/2))
$239.4 : $227.88
The second store is less expensive

Answer 2

The second store is cheaper. It is only 18.99 per gallon. Just divide the costs by 2.
