A) If Pamela has 20 inches of string, does she have enough to make bracelets for 4 of her friends? B) If so, how much string would she had left over? If not, hoe much more string would she need? [Please explain clearly and be specific on how you get the answer to part A and B.]

Respuesta :

a. yes, because 4x5=20 so it is enough for her friends. B 4x2 = 8 (from 5.2) so Pamela has 0.8 string left

Answer:

Each friendship bracelet needs 5.2 inches of string.

For 4 bracelets, she will need [tex]5.2\times4=20.8[/tex] inches

A) If Pamela has 20 inches of string, does she have enough to make bracelets for 4 of her friends?

No, because for each bracelet, she will have only [tex]\frac{20}{4}=5[/tex] inches. But that is less as she needs 5.2 inches per bracelet.

B) She will need [tex]20.8-20=0.8[/tex] inches more.

Hence, she will need 0.8 inches of string more to make 4 bracelets.
