Question

Make P the subject of the formula
A = P +PRT/100

Answer 1

Answer:

It's easy take P common A= P(1+RT/100)

SO P= 100A/(1+RT)

Answer 2

The required formula, P = A/(1 + RT/100)  

Given:

A = P +PRT/100

To find:

Make P the subject of the formula

Solution:

To make the P the subject of the formula,

Start with the formula

A = P + PRT/100

Isolate P on one side of the equation.

Take P as common

=> A = P(1 + RT/100)

Now divide the equation by (1 + RT/100) into both sides

=> A/(1 + RT/100) = P(1 + RT/100)/(1 + RT/100)

=> A/(1 + RT/100) = P

This can be rewritten as

=> P = A/(1 + RT/100)  

Therefore,

The required formula, P = A/(1 + RT/100)
