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?

Hi! I think I can help you with this! :)

OpenStudy (anonymous):

Awesome!

Before we look at how many feet of white ribbon she needs for 18 wreaths, let's start with a simpler question: how many feet of white ribbon does she need for 1 wreath? :)

OpenStudy (anonymous):

A) 30 ft B) 50 ft C) 70 ft. D) 90 ft.

OpenStudy (anonymous):

45 in

OpenStudy (anonymous):

Okay, well done, now let's try and convert 45 inches into feet :)

OpenStudy (anonymous):

3.75 feet

OpenStudy (anonymous):

Well done! :)

Since this question just wants an approximate answer, let's simplify our life a bit and just call it "a bit less than 4 feet".

OpenStudy (anonymous):

So if it takes a bit less than 4 feet to make one wreath, how many feet will you need to make 18 wreaths?

OpenStudy (anonymous):

72

OpenStudy (anonymous):

Excellent! So she needs a bit less than 72 feet, and you can now pick the best answer from your four choices :)

OpenStudy (anonymous):

So "C' would be the best option

OpenStudy (anonymous):

Yep! Well done! (Sorry about the delay, by the way - my internet died :/)
