Question

The formula for calculating simple interest is I = prt. Which is the equivalent equation solved for r? l/pt=r pt/l=r l-pt=r l+pt=r
Please hurry!!!!

Answer 1

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.

Answer 2

I=prt

solving for r

we need to isolate r on the left side

so dividing both sides by pt , we get

r=I/pt
