(a) Write an expression in terms of d to represent the value of the stock after two years. (b) If an initial investment is $1,000, determine its value at the end of 2 years.

Respuesta :

Answer:

1. 3D-1200 = value after two years.

2. $1800 = value after two years

Step-by-step explanation:

When the value of D triples, 3 times D = 3D. value of the stock after two years decreased, would be the -1200.

When you get the value of 1,000 you can plug it in to get 3 (1000) - 1200 = Stock price after two years
