Question

Please hurry on an exam The formula for calculating simple interest is I = prt. Which is the equivalent equation solved for r?

StartFraction I Over p t EndFraction = r
StartFraction p t Over I EndFraction = r
I minus p t = r
I + p t = r

Answer 1

r=I/pt

Explanation:

I = PRT is the formula for interest, and we need to solve it for R. Since all three of P, R, and T are multiplied, we send things to the other side of the equals through dividing. I = PRT I / P = RT to divide both sides by P I / PT = R to divide both sides by T So I / PT = R (the first choice) is the equation solved for R.
