The fundamental behavior that's important here is that, as $t$ gets arbitrarily large, $a^t$ becomes smaller (decays) if $|a|$ and larger (grows) if $|a|>1$ .

$100\left(1-\dfrac12\right)^t=100\left(\dfrac12\right)^t\implies\dfrac12$

$0.1(1.25)^t\implies1.25>1\implies\text{growth}$

$426(0.98)^t\implies0.98$

$2050\left(\dfrac12\right)^t\implies\text{decay}$

$\left((1-0.03)^{1/2}\right)^{2t}=0.97^t\implies0.97$

What is the equivalent amount in year ten of an expenditure of $5,000 in year one, $6,000 in year two, and amounts increasing by

Archy [21]

Answer:

The correct answer is the equivalent amount is $139,059.41

Step-by-step explanation:

According to the scenario, the computation of the equivalent amount in year ten is shown below;

= $5,000 × (P/A, 10%,10) + $1,000 × (P/G, 10%,10)

= $5,000 × 6.1466 + $1,000 × 22.8913

= $30,723 + $22,891.30

= $53,614.30

Now the equivalent amount is

= $53,614.30 × (F/P, 10%,10)

= $53,614.30 × 2.5937

= $139,059.41

Hence, the equivalent amount is $139,059.41
