The method for finding the answer is as shown in the response from the other tutor.
If this is a multiple choice question on a timed test, then the correct answer choice can be found quickly with a bit of estimation and simple mental arithmetic.
If the interest were simple interest instead of compound interest, then the interest on $1500 at 5% per year would be $75 a year, or $300 for 4 years. So answer choice B would be the answer for simple interest. Since the problem is with compound interest, the amount at the end of 4 years must be a bit more than $1800. So answer choices A and B can't be right.
Answer choice C is a bit more than $1800, as required; answer choice D is unreasonable. So
ANSWER: C
