Answer:
[tex]A = \frac{100 P}{100+r}[/tex]
Step-by-step explanation:
Given [tex]P = A( 1 + \frac{r}{100} )[/tex]
To make A as the subject of the formula we need to rearrange
Divide by [tex](1 +\frac{r}{100})[/tex] throughout we get
[tex]\frac{P}{1+\frac{r}{100}} = A[/tex]
[tex]A = \frac{100P}{100 + r}[/tex]
