Question

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

Answer 1

r = 100(
`(A)/(P)` - 1 )

Explanation:

Given

A = P(1 +
`(r)/(100)` ) ← divide both sides by P

`(A)/(P)` = 1 +
`(r)/(100)` ( subtract 1 from both sides )

`(P)/(A)` - 1 =
`(r)/(100)` ( multiply both sides by 100 )

100 (
`(P)/(A)` - 1) = r
