Answer:
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
