A school club needs 300 feet of rope for a project. They have the amounts of rope listed below.

Minchanka [31]

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.

$\text{2 pieces of 16 yards}=2\times16\text{ yards}=32\text{ yards}$

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.

$\text{Total amount of rope that school club already have}=96+37.5+123.25$

$\text{Total amount of rope that school club already have}=256.75$

Now let us subtract 256.75 feet from 300 feet to find the amount of rope that school club needs to complete the project.

$\text{Amount of rope school club needs to complete the project}=300-256.75$

$\text{Amount of rope school club needs to complete the project}=43.25$

Therefore, the school club needs 43.25 feet of additional rope to complete their project.
