Answer: You will need 220 feet of ribbon and 5 rolls.

Step-by-step explanation:

Hi, to answer this question we have to multiply the amount of ribbon that each box needs (2 3/4) by the number of boxes (80).

Mathematically speaking:

2 3/4 x 8 = (2x4+3)/4 x 8 = 11/4 x 80 = 880/4 = 220 feet of ribbon

You will need 220 feet of ribbon.

Since each roll of ribbon has 50 feet, we have to divide the total amount of ribbon needed (220) by the amount of ribbon that each roll has (50), to calculate the number of rolls needed.

220/50 = 4.4 rolls =5 rolls (1 roll is not fully used)
