Some investments in the stock market have earned 10% annually. At this rate, earning can be found using the formula A=p(1.10)n,
GalinKa [24]

Answer:

<em>c. 13.899.79</em>

Step-by-step explanation:

<u>Exponential function </u>

Two variables y and x have an exponential relation if  

y=Ce^{kx}

where C and k are real numbers. Many natural phenomena are modeled by using exponentials, finance included, where the growing of the investments can be computed through the use of the exponential function

The situation described in the question is modeled as

A=p1.1^{n}

being A is the total value of the investment, p is the initial value of the investment, and n is the number of years the money is invested. We know p=2,500 and n=18, so we compute A

A=(2,500)1.1^{18}

A=$13,899.79

Answer: c. 13.899.79

This is because (15-3)= 12
12x4=48
48+9= 57
