Question 1004824: The number of students attending a leadership conference depends on the price charged. It is determined that 20 students will attend the conference if each is charged $75. For each $10 increase in price, 1 fewer student will attend. This situation is represented by the equation y=(75 + 10x)(20 - x). The cost of running the conference is represented by the equation y = 1000 + 75x.
For each equation, identify what each variable represents.
