The cost C (in dollars) of producing x DVD players is represented by C = 4.5x2. How many DVD players are produced if the cost is

lisabon 2012 [21]

Given the following equation representing the cost of producing DVD Players:

$\text{ C = 4.5x}^2$

Let's determine the number of DVD players produced if the cost is $544.50

$\text{ C = 4.5x}^2$ $\text{ \$544.50 = 4.5x}^2$ $\text{ }\frac{\text{\$544.50}}{\text{ 4.5}}\text{ = }\frac{\text{4.5x}^2}{\text{ 4.5}}$ $\text{ 121 = x}^2$ $\text{ }\sqrt{\text{121}}\text{ = }\sqrt{\text{x}^2}$ $\text{ 11 = x}$

Therefore, it'll cost $544.50 to produce 11 DVD Players.

The answer is 11.
