Solve the simple interest formula, [tex]\( I = Prt \)[/tex], for [tex]\( P \)[/tex].

A. [tex]\( P = I r t \)[/tex]

B. [tex]\( P = \frac{I}{r t} \)[/tex]

C. [tex]\( P = \frac{r}{I t} \)[/tex]

D. [tex]\( P = \frac{t}{I r} \)[/tex]



Answer :

To solve for [tex]\(P\)[/tex] in the simple interest formula [tex]\(I = Prt\)[/tex], follow these steps:

1. Start with the given formula:
[tex]\[ I = Prt \][/tex]
Here, [tex]\(I\)[/tex] represents the interest, [tex]\(P\)[/tex] is the principal (the initial amount of money), [tex]\(r\)[/tex] is the rate of interest per period, and [tex]\(t\)[/tex] is the time the money is invested for.

2. We need to isolate [tex]\(P\)[/tex] on one side of the equation. To do this, divide both sides of the equation by [tex]\(rt\)[/tex]:
[tex]\[ \frac{I}{rt} = \frac{Prt}{rt} \][/tex]

3. Simplify the right side of the equation. Since [tex]\(rt\)[/tex] cancels out on the right side, we have:
[tex]\[ \frac{I}{rt} = P \][/tex]

4. We have successfully isolated [tex]\(P\)[/tex] and found the expression:
[tex]\[ P = \frac{I}{rt} \][/tex]

So the correct expression for [tex]\(P\)[/tex] is:
[tex]\[ P = \frac{I}{rt} \][/tex]

From the given options, the correct one is:
[tex]\[ P = \frac{I}{rt} \][/tex]
