I took the test last year
<h3>What would be the value of $150 after eight years if you earn 12 % interest per year? A. $371.39 B. $415.96 C. $465.88 </h3>
<em>The compound interest is applied, that is to say, each year the interest produced is accumulated to the outstanding capital and the interest of the next period is calculated on the new outstanding capital.</em>
The formula for calculating compound interest is:
Compound interest = Total amount of Principal and interest in future less Principal amount at present = [P(1 + i)ⁿ] – P
(Where P = Principal, i = nominal annual interest rate in percentage terms, and n = number of compounding periods)
[P(1 + i)ⁿ] – P = P[(1 + i)ⁿ – 1] = $150[(1 + 12/100)⁸ – 1] = $150[(1.12)⁸ – 1] = $150[2.47596317629 - 1] = $150[1.47596317629] = $221.39
Total amount = $150 + $221.39 = $371.39
Answer : A.) $371.39

Complete Question
On Tuesday Jack bought four boxes. On Wednesday half of all the boxes that he had were destroyed.
Write an expression for how many boxes Jack has now
A. 1/2b+4
B. 1/2+4b
C. 4b−1/2b
D. b+42/2
Answer:
C. 4b−1/2b
Step-by-step explanation:
Let the number of boxes that Jack has be represented by b
In the question, we are told that:
• On Tuesday, Jack bought 4 boxes
Since 1 box = b
4 boxes = 4b
• On Wednesday , half of the boxes where destroyed.
= 1/2 b
The expression for how many boxes Jack has now is given as
Number of boxes Jack bought in Tuesday - half of the boxes destroyers on Wednesday.
This is expressed mathematically as:
4b - 1/2b
