Question

Christi cuts 7 inches off the bottom of a skirt and then adds a 5-inch ruffle to the remaining bottom edge. What expression best represents the final length of the skirt?

a. 2 - 3
b. 2 - s
c. s - 2
d. s - 12

Answer 1

The final expression representing the length of the skirt after cutting off 7 inches and adding a 5-inch ruffle is s - 2.

Step-by-step explanation:

To calculate the final length of the skirt, we need to subtract 7 inches (representing the amount cut off) from the original length of the skirt, and then add 5 inches (representing the length of the ruffle) to the result. So, the expression that represents the final length of the skirt is s - 7 + 5, which simplifies to s - 2. Therefore, the correct option is (c) s - 2.
