Answer:

Infinitely many.

Step-by-step explanation:

3x + 2y = 4

-6x - 4y = -8

Note that the second equation is obtained from the first by multiplying the first one by -2. Thus the graph of the 2 equations is the same line and there are infinitely many solutions.

The profit of a company receives is given by the expression 0.15(855p - 315) where p is the number of problems sold. Rewrite thi
Goryan [66]

The profit for 25 products sold and 150 products sold are 3159 and 19190.25 respectively.

<u><em>Explanation</em></u>

The profit of a company receives is given by the expression:  0.15(855p - 315)

Simplifying this expression using distributive property, we will get .....

0.15(855p - 315) \\ \\ = (0.15*855p)-(0.15*315)\\ \\ =128.25p-47.25

So, the simplified expression for profit will be:  128.25p-47.25

As p represents the number of products sold, so for finding the profit for 25 products sold and 150 products sold, <u>we need plug p=25 and p=150 separately into the above expression</u>.  

For p=25,  Profit =128.25(25)-47.25 = 3206.25-47.25= 3159

For p=150, Profit =128.25(150)-47.25 = 19237.50-47.25= 19190.25
