Ruby is decorating for a party and needs 120 meters of ribbon. at the party supply store, the ribbon is sold in rolls. each roll contains 25 feet of ribbon. how many rolls will ruby need to purchase? (1 meter is approximately 39.37 inches)

She will need to purchase 16 rolls of ribbon

Step-by-step explanation:

Step 1: Express the total length of ribbon

Use the expression below;

T=R×N

where;

T=total length of ribbon Ruby has

R=length per roll

N=number of rolls

In our case;

T=120 meters, but since 1 meter=3.28084 feet

T=(120×3.28084)=393.7008 feet

R=25 feet

N=n

replacing;

393.7008 =25×n

n=393.7008/25

n=15.748 rounded up=16

She will need to purchase 16 rolls of ribbon
