Christy bought an 8-foot piece of lumber to trim a bookshelf. Altogether, she needs 100 inches of lumber for the trim.

Did Christy buy enough lumber? Explain.

Answer (2)

The answer is No. Christy needs 100 inches of lumber. She bought an 8 ft piece of lumber. Let's convert 8 ft to inches. 1 ft = 12 in. 8 ft = 8 * 12 in = 96 in. So, Christy has 96 inches of lumber, but she needs 100 inches of lumber. This means that she needs 4 inches more than she has (100 in - 96 in = 4 in).

Christy bought 96 inches of lumber, but she needs 100 inches for the trim. Therefore, she is short by 4 inches and did not buy enough lumber. She needs to get an additional 4 inches to meet her requirement.
