Answer

Explanation:

Step1: Isolate t in the formula

Given $I = Prt$, divide both sides by $Pr$ to solve for $t$. So $t=\frac{I}{Pr}$.

Step2: Substitute values into the new - formula

We have $I = 75$, $P = 500$, and $r=0.05$ (since $5%=0.05$). Substitute these values into $t=\frac{I}{Pr}$. Then $t=\frac{75}{500\times0.05}$.

Step3: Calculate the value of t

First, calculate $500\times0.05 = 25$. Then $t=\frac{75}{25}=3$.

Answer:

a. $\frac{I}{Pr}$ b. 3
