Mrs. Reed is decorating wreaths. She needs 24 in. of gold ribbon and 45 in. of white ribbon to tie around each wreath. The white ribbon is sold by the foot. About how many feet of white ribbon will Mrs. Reed need to make 18 wreaths?

A)

30 ft

B)

50 ft

C)

70 ft.

D)

90 ft.

The correct answer is C.

If she needs 45 in of white ribbon for each wreath, then she will need close to 4 feet of ribbon for each wreath. This is because 12 in = 1 foot, and 45 divided by 12 is 3.75.

If she's going to be making 18 wreaths, then she will need 3.75 feet of white ribbon for every wreath:

3.75 x 18 = 67.5.
