Answer 1

Answer:

A. 220 feet

B. 220 feet

C. 5 rolls of ribbon

Step-by-step explanation:

Given.

Number of box $= 80$

We need $2\frac{3}{4}$ feet of ribbon for each box wrapping.

Each roll of ribbons is 50 feet.

A.

Estimated value of ribbon for 80 boxes.

= Number of box $\times$ ribbon for each box

$= 80\times 2\frac{3}{4}$

$= 80\times \frac{11}{4}$

$= 20\times 11$

$= 220 feet$

The estimated number of feet of ribbon for 80 boxes is 220 feet.

B. Exact the number of feet of ribbon for 80 boxes is 220 feet.

C.

Number of rolls for wrapping 80 large boxes.

Each roll of ribbon is 50 feet and we are required 220 feet of ribbons.

rolls of ribbon = total required ribbon divided by how much feet in rolls.

rolls of ribbons = $\frac{220}{50}$

rolls of ribbons = $4.4$

Therefore, the total required rolls for 220 feet of ribbons is 5
