A company needs to make at least A company needs to make at least 75,000 bottles 20-oz bottles can made from 1 pound if plastic
strojnjashka [21]

Answer:

By using the recycled plastic the company will save $1050.

Step-by-step explanation:

A company needs to make at least 75,000 bottles.

Now, 20-oz bottles can be made from 1 pound.

Then, 75000-oz bottles can be made from \frac{75000}{20} = 3750 pounds of plastic.

Now, the cost of new plastic is $0.83 per pound.

So, cost of new plastic to make 75000 bottles will be $(3750 × 0.83) = $3112.5.

Again,  the cost of recycled plastic is $0.55 per pound.

So, cost of recycled plastic to make 75000 bottles will be $(3750 × 0.55) = $2062.5.

Therefore, by using the recycled plastic the company will save $(3112.5 - 2062.5) = $1050. (Answer)
