Question

A company builds rectangular shaped storage buildings for home owners at $20 per square foot. Rick wants to have a storage building built on his property but has a budget of $2,000. If he wants the building's length to be 6 feet longer than its width, then which of the inequalities can be used to solve for the width of the building?

Answer 1

First, you find how many total feet Rick can afford. To do this, you do 2000/20 which equals 100. Then, you write your inequality. 100 is less than or equal to 2x+6. Next, you solve your inequality. You subtract 6 on both sides to get 94 equals 2x. To solve this, you divide by 2 on both sides. In this scenario, x stands for the width.
