Question

Make R the subject of the formula , A equals to P( l+r/100)​

Answer 1

Answer:

r = 100($\frac{A}{P}$ - 1 )

Step-by-step explanation:

Given

A = P(1 + $\frac{r}{100}$ ) ← divide both sides by P

$\frac{A}{P}$ = 1 + $\frac{r}{100}$ ( subtract 1 from both sides )

$\frac{P}{A}$ - 1 = $\frac{r}{100}$ ( multiply both sides by 100 )

100 ( $\frac{P}{A}$ - 1) = r
