Daniel is building a “learning tower.” A learning tower is a small structure that allows small children to help in the kitchen. The design plans that Daniel is using requires 12 boards of high quality lumber. At the local home improvement store, about 88% of the lumber would be high quality, meaning it would be free of defects and usable in this project. To account for lumber that may be discarded, Daniel purchases 15 boards of lumber from this store. (Assume that Daniel is in a hurry and does not have time to closely inspect the boards while at the store.)
