Amovie theater has a total of 347 seats. for a special saturday night preview, they reserve 36 seats to give away to their vip guests at no charge. if x represents the number of tickets they can sell for the preview, then x can be found by solving the equation x + 36 = 347. a.) solve the equation for x. if tickets for the preview are $11.00 each, what is the maximum amount of money they can make from ticket sales? b)the max they can make from ticket sales is $

a) x + 36 = 347

b) revenue = $11x

a) x

b) revenue

a) subtract 36 from both sides of the equation

... x + 36 - 36 = 347 - 36

... x + 0 = 311

... x = 311

b) substitute the value for x and do the arithmetic

... revenue = $11·311

... revenue = $3421

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.
