Lisha is making headbands using ribbon. she would like to make 12 head bands. each one requires 15.5 inches of ribbon. she estimates that she will need to buy 160 inches of ribbon is her estimate reasonable? explain your reasoning and lol i'm not in college i just did that

No her estimate is to low because if you multiply 15.5 by 12 you get 186

We know that Lisha is making headbands using ribbon and she would like to make 12 head bands. Additionally, each one requires 15.5 inches of ribbon. She estimates that she will need to buy 160 inches. 

15.5 * 12 = 186 

Her estimate is not reasonable.

186-160 = 26 

She still needs 26 more ribbons.
