I=prt,for p please show step by step for this variable

Bond [772]

Answer:

$p = \dfrac{I}{rt}$

Step-by-step explanation:

I = prt

Switch sides.

prt = I

We are solving for p. We want p alone on the left side. p is being multiplied by r and t, so we divide both sides by r and t.

$\dfrac{prt}{rt} = \dfrac{I}{rt}$

$p = \dfrac{I}{rt}$
