Given the following equation representing the cost of producing DVD Players:
[tex]\text{ C = 4.5x}^2[/tex]
Let's determine the number of DVD players produced if the cost is $544.50
[tex]\text{ C = 4.5x}^2[/tex][tex]\text{ \$544.50 = 4.5x}^2[/tex][tex]\text{ }\frac{\text{\$544.50}}{\text{ 4.5}}\text{ = }\frac{\text{4.5x}^2}{\text{ 4.5}}[/tex][tex]\text{ 121 = x}^2[/tex][tex]\text{ }\sqrt{\text{121}}\text{ = }\sqrt{\text{x}^2}[/tex][tex]\text{ 11 = x}[/tex]
Therefore, it'll cost $544.50 to produce 11 DVD Players.
The answer is 11.
