So given the values on the number line, AB and BC, adding them together will get the length of AC. If AB equals 
and BC equals 
, the value of AC should be 
. Since you are given the length of AC, 
, you can create an equation to solve for x. This equation would be 
. Isolating the x on the left (or right hand side) gets the value of x to be 19. The same thing goes for the 2nd question.
<h3>Answer: Choice B. </h3>
=================================
Explanation:
You could use the formula
to plug in P = 1500, r = 0.02 and n = 12 to get the answer above. This is the compound interest formula. The interest rate r is divided into n = 12 to account for monthly compounding. The original exponent t turns into 12t. So for instance, if t = 2 years go by, then 12*t = 12*2 = 24 months have gone by.
