Solution

(a)

To Find: A rational equation to find the value of x , where x is the number of ounces of zinc needed.

The required rational equation is x=45100×y.

Given information:

Brass is an alloy composed of 55% copper and 45% zinc by weight. There are 25 ounces of copper.

Explanation:

Let y represent the weight of brass and x represent the number of ounces of zinc needed.

Therefore, the number of ounces of zinc needed will be given by: x=45100×y.

(b)

To calculate: The number of ounces of zinc needed to make brass.

The number of ounces of zinc needed to make brass is 20.45.

Given information:

Brass is an alloy composed of 55% copper and 45% zinc by weight. There are 25 ounces of copper.

Explanation:

Let y represent the weight of brass and x represent the number of ounces of zinc needed.

The copper available is 25 ounces.

  ⇒55100×y=25

Solve it for y.

  y=25×10055

The zinc required will be 45% of y.

So,

  x=45100×y=45100×25×10055≈20.45

Therefore, the number of ounces of zinc needed to make brass is 20.45.

(c)

To Find: The ounces of zinc that must be added to make brass, where c is the ounces of copper available.

The zinc needed to make brass is 0.82c ounces.

Given information:

Brass is an alloy composed of 55% copper and 45% zinc by weight.

Explanation:

Let y represent the weight of brass and x represent the number of ounces of zinc needed.

The copper available is c ounces.

  ⇒55100×y=c

Solve it for y.

  y=c0.55

The zinc required will be 45% of y.

So,

  x=45100×y=45100×c0.55≈0.82c

Therefore, the zinc needed to make brass is 0.82c ounces.
