Question

The formula A=P+Prt gives the final value, A, after investing P dollars for t years at a simp interest rate r. Rearrange this formula to solve for t. Enter your answer as an equation with only t on the left hand side.

Answer 1

To solve for t in the simple interest formula A = P + Prt, subtract P from both sides to get A - P = Prt, and then divide both sides by Pr to get t = (A - P) / (Pr).

Step-by-step explanation:

The formula given is A = P + Prt, which is used to calculate the future value, A, after investing P dollars for t years at a simple interest rate r. To rearrange this formula to solve for t, you would follow these steps:

1. Subtract P from both sides of the equation to isolate the term containing t: A - P = Prt.
2. Divide both sides of the equation by Pr to solve for t: t = (A - P) / (Pr).

Therefore, the rearranged formula to solve for t is t = (A - P) / (Pr).
