for each situation, write the equation to represent each situation. then use your equation to answer each question. be sure to define your variables, identifying which is independent and which is dependent. show all work. round any decimals to the nearest hundredth and choose the correct answer from the choices below.
a stadium that seats 35,000 is slowly filling up with fans. the game starts at four o'clock. at noon the stadium owner estimates there are 4,000 fans who have already arrived early. at one o'clock he estimates just over 11,000 fans have found their seats and they appear to be coming in at a steady rate. he knows his stadium will be more than ninety percent full by game time. choose the function below that best models this situation and tracks attendance from noon to game time.
a) f(x)=7,000x+4,000
b) f(x)=4,000x+4,000
c) f(x)= 0.90x+4,000
d) f(x)=11,000x+4,000
