<font face="Garamond" size="+2">


Just plug in the given value for the number sold into every place you see an *[tex \Large x]


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ R\ =\ 205.46x\  -\ 0.2x^2]


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ R\ =\ 205.46(208)\  -\ 0.2(208)^2]


I'll leave you alone to spend some quality time with your calculator.
