Answer 2

Given - Amount = $ 8400

Interest = $ 700

Find - Amount Sam invested

Solution - The amount Sam invested can be calculated by the formula - Amount = Principal + Interest

So, keep the values in the formula to find the amount invested by Sam. This invested amount is called the principal.

Hence, Principal = Amount - Interest

Principal = 8400 - 700

Principal = $ 7700

Hence, as per the question the amount invested by Sam is ( D ) $7,700.
