This is confusing an airplane has room for 300 coach- fair seats. it can replace any 3 coach seats with 2 first class seats. suppose the airplane is configured with x coach seats and y first class seats. (assume no space is wasted) a) if y=0, what is the value of x? explain the significance in terms of the airplane’s seat configuration. b)if x=0 ,what is the value of y? explain the significance in terms of the airplane’s seat configuration. c)it can be shown that y is a linear function of x. sketch a graph y versus x, labeling both axis-intercepts. d) find a formula for y in terms of x
