Answer:
43.25 feet.
Step-by-step explanation:
We have been given that school club needs 300 feet of rope for a project.
First of we will change given lengths of ropes in feet.
[tex]\text{2 pieces of 16 yards}=2\times16\text{ yards}=32\text{ yards}[/tex]
1 yard =3 feet
32 yards= 3*32 feet = 96 feet.
12.5 yards = 3*12.5 feet = 37.5 feet.
Let us find the amount of rope school already have by adding all the given amounts.
[tex]\text{Total amount of rope that school club already have}=96+37.5+123.25[/tex]
[tex]\text{Total amount of rope that school club already have}=256.75[/tex]
Now let us subtract 256.75 feet from 300 feet to find the amount of rope that school club needs to complete the project.
[tex]\text{Amount of rope school club needs to complete the project}=300-256.75[/tex]
[tex]\text{Amount of rope school club needs to complete the project}=43.25[/tex]
Therefore, the school club needs 43.25 feet of additional rope to complete their project.
