Question

22. I = Prt; P What do I first? It says to solve the equation for the given variable.

Answer 1

the first thing you need to do is

divide the whole equation by rt as shown below

$\frac{i}{rt} = \frac{prt}{rt}$

then you cancel out. leaving

$\frac{i}{rt} = p$

which is the same as

$p = \frac{i}{rt}$
