Question

SOLVE I=PRT FOR R
R=

Answer 1

Do they give you any numbers? Think of it like \[R(PT)=I\] So you can divide both sides by PT to get R by its self.

Answer 2

@JBrandonS IM LOST

Answer 3

\[\frac{R(PT)}{PT}=\frac{I}{PT} \rightarrow R=\frac{I}{PT}\] IF they gave you numbers now you can plug them in.

Answer 4

thanks @JBrandonS
