To find the compound interest over a certain period of time we need to apply the following expression:
[tex]M\text{ = P}\cdot(1+r)^t[/tex]Where M is the final value, P is the principal, r is the interest rate divided by 100 and t is the elapsed time in years. Applying the data from the problem gives us:
[tex]\begin{gathered} M\text{ = 950}\cdot(1\text{ + }\frac{6.8}{100})^{10} \\ M\text{ = 950}\cdot(1+0.068)^{10} \\ M\text{ = 950}\cdot(1.068)^{10}\text{ = }1834.1554 \end{gathered}[/tex]The interest on over the course of these years were:
[tex]\text{interest = 1834.1554 - 1750 = }84.16[/tex]
