Question

Nasim bought stock in a company two years ago that was worth x dollars. During the first year that he owned the stock, it decreased by 28%. During the second year the value of the stock increased by 35%. Write an expression in terms of x that represents the value of the stock after the two years have passed.

Answer 1

The expression that represents the value of the stock after two years is 0.972x.

Step-by-step explanation:

The expression that represents the value of the stock after the two years is:

x - 0.28x + 0.35(0.72x) = x - 0.28x + 0.252x

This can be simplified to:

x - 0.28x + 0.252x = x - 0.028x

Combine like terms:

0.672x = 0.972x

So, the expression that represents the value of the stock after the two years is 0.972x.
