Answer 1

The Solution:

Given:

$P=\frac{8.4Y+330T+100C-200I}{A}$

We are required to make C the subject of the formula.

$\begin{gathered} P=\frac{8.4Y+330T+100C-200I}{A} \\ \\ Cross\text{ multiply.} \\ \\ 8.4Y+330T+100C-200I=PA \end{gathered}$

Thus,

$100C=PA+200I-(8.4Y+330T)$

Divide both sides by 100.

$C=\frac{PA+200I-8.4Y-330T}{100}$

Therefore, the correct answer is:

$C=\frac{PA+200I-8.4Y-330T}{100}$
