You have to choose how to invest a sudden windfall, and the two investments between which you are trying to decide have the following terms. Investment A will pay a monthly dividend of
$100 along with 0.1% of the principal (the principal is the amount invested). The other pays a
straight 0.2% of the principal.
Which of these is likely to be best for small amounts of principal?
Which is likely to be best for large amounts? Explain.
Find the boundary - the amount at which the two pay the same.

(a) {a₁, a₁r, a₁r², … a₁rⁿ⁻¹, …}

(b) $59 398

step-by-step explanation:

(a) the annual sequence of profits

aₙ = a₁rⁿ⁻¹

the model for the sequence of profits is {a₁, a₁r, a₁r², … a₁rⁿ⁻¹, …} .

(b) profit after 15 yr

  a₁ = $ 30 000

  r = 1.05

a₁₅ = 30 000 × 1.05¹⁴

a₁₅ = 30 000 × 1.979 93

a₁₅ = $59 398

the profit in year 15 will be $59 398.

first the equation needs to be simplified. so the equation would now look like:   52-24+11

then you multiply.

and when you multiply, you will get the answer of 39.
