A wooden door stopper needs to be covered with stickers to match the door for a directing contest. If one package of stickers covers a surface area of 75 square centimeters, how many packages of stickers need to be purchased? (Find the closest number to the surface area of the door stopper. Stickers may only be purchase in whole packs.)

The surface area of the wooden door stopper needs to be calculated first. Let's say the surface area of the door stopper is 90 square centimeters.
Next, we need to calculate how many packages of stickers are needed to cover this surface area. Since one package of stickers covers 75 square centimeters, we can divide the total surface area of the door stopper by the coverage area of one package:
90 square centimeters / 75 square centimeters = 1.2
Since stickers can only be purchased in whole packs, we need to round up to the nearest whole number. Therefore, we would need to purchase 2 packages of stickers to cover the entire surface area of the wooden door stopper.
