Step-by-step explanation:
The formula for compound interest is P(1 + r)^t, where P = Principal (initial amount), r = rate (percentage rate), and t = time (years). Let's start off by adding 1 to the percentage rate in decimal form. 1.5% is 0.015 in decimal form. 1 + 0.015 is 1.015. The amount of time is 2 years, so we raise that decimal to the 2nd power. 1.015^2 is 1.030225. Do not delete this decimal from the calculator. Now, let's multiply it by the principal, which is 12,000 British pounds. When you multiply that decimal by 12,000, you get 12,362.70. There. Mary's investment will be a value of £12,362.70

With Khan Academy, there is a small trick that can be done to see answers, you just have to click the percentage before going back into the lesson and it shows the answers you have gotten wrong, and giving you the answer for them. Opening up two tabs allows a fluent work space. Hope this sort of helps. I’m not good at math.
