why all those steps in question 13 only (1.02^3 × 6250) and you will get the answer
To maximize the chance of getting working marks for interest questions (if the answer is wrong), I teach students to show the working for each year separately.

You can use the formula method then to confirm the answer.

6632.55 was the exact answer so you'll lose 1 mark for unnecessary rounding.
