Formula look like this:[deqn]A=P\left( 1+\frac{r}{100} \right)^n[/deqn] So, your 1st equation is:[deqn]4800=P\left( 1+\frac{r}{100} \right)^2[/deqn] And your 2nd equation look like this:[deqn]5200=P\left( 1+\frac{r}{100} \right)^3[/deqn] By taking the 2nd equation divided by the 1st equation, you get:[deqn]\frac{5200}{4800}=1+\frac{r}{100}[/deqn] Solving for the r, you get [ieqn]8\frac{1}{3}[/ieqn]
