Question

Write the correct system of inequalities, by first defining x and y, that correctly models the situation. Then write the inequalities and then graph the situation stated below. For your stock portfolio, you have at most $4000 that you want to use to buy stock in two companies. One is a construction company, the other is a biotech company. You want to have at least 2 times as much in the construction company as you do in the biotech company. System of inequalities:

Answer 1

SOLUTION

Let x be a construction company,

Let y be a biotech company

From the question, we have that :

$\begin{gathered} x\text{ + y }\leq\text{ 4000}\ldots\ldots..\ldots\ldots\ldots\ldots..equ\text{ 1 } \\ x\text{ }\ge\text{ 2y}\ldots\ldots\ldots\ldots\ldots\ldots\ldots\ldots\ldots\ldots equ\text{ 2} \end{gathered}$
