The given equations are,

and

Multipying the second equation by 3 . we get,

Now, If we add both the sides of both the equations. we get,

or

Which implies,

Substituting the value of x in any of the above equations. We get,

**Answer:**

d. $137,604

**Step-by-step explanation:**

The amortization formula is good for this. It tells you the principal P that must be invested to support payments of A each year for t years when the interest rate is r:

P = A(1 -(1 +r)^-t)/r

P = $12,000(1 -1.06^-20)/0.06 ≈ $137,639.05

The closest answer choice is **$137,604**.

18+18=36. 20% is 9 apples. 36+9=45. 45 apples at the stand. (not good for business)
