Question

how do i solve for r ????
P=A/l+rt

Answer 1

\[\large P=\frac{A}{1+rt}\]


\[\large P(1+rt)=A\]


\[\large P+Prt=A\]


\[\large Prt=A-P\]

\[\large r=\frac{A-P}{Pt}\]

Answer 2

or A=P+Prt

Answer 3

P=A/l+rt --> P(l+rt)=A --> l+rt=A/P --> rt=(A/P)-l --> r --? ((A/P)-1)/t

Answer 4

@emmanuell that's the flipped version of the 3rd line of what I wrote
