Use A as the subject of formula<br>p= A ( 1+r\100)​
ZanzabumX [31]

Answer:

A = \frac{100 P}{100+r}

Step-by-step explanation:

Given P = A( 1 + \frac{r}{100} )

To make A as the subject of the formula we need to rearrange

Divide by (1 +\frac{r}{100})  throughout  we get

\frac{P}{1+\frac{r}{100}} = A

A = \frac{100P}{100 + r}
