a pet store runs a monthly magazine ad that is 2 inches wide and 6 inches long and costs $366. The cost of each ad is based on its area. If the pet store manager decides to triple the width of the ad, how much will the new ad cost?
If you take the initial cost and divide it by the initial area (366/12) then you get the ratio. When you find the new area (6•6=36) you multiply that by the ratio you got earlier. So 36•30.5 which gives you the answer of 1,098
