C. 18 inches
D. 5 inches

Answer 1

Alice bought 4.5 feet of ribbon, which is 54 inches. She needs 36 inches for her art project, and thus she will need to cut off 18 inches of ribbon.

Step-by-step explanation:

Alice needs 36 inches of ribbon to complete her art project, and at the store she buys four and a half feet of ribbon. To calculate how many inches of ribbon Alice will need to cut off, we must first convert the feet to inches. Since there are 12 inches in one foot, we can use this information to set up our conversion:

4.5 feet x 12 inches/foot = 54 inches.

This means Alice bought 54 inches of ribbon. Since she only needs 36 inches, we subtract the length she needs from the length she bought:

54 inches - 36 inches = 18 inches.

Therefore, Alice is going to have to cut off 18 inches of ribbon, which corresponds to option C.
