Renna pushed the button for the elevator to go up, but it would not move. the weight limit for the elevator is 450 kilograms, but the current group of passengers weighs a total of 750 kilograms. renna wants to determine how many 70-kilogram passengers need to get off the elevator. let p represent the number of excess passengers. write an inequality to determine the number of passengers who need to get off the elevator to meet the weight requirement.

First we should figure out how much over the weight limit the passengers are. We can find this by 750-450 which is 300. The amount of weight that needs to get off the elevator is 300 kilograms. Then, we know that each passenger weighs 70 kilograms. We can represent this as 70p.The inequality is 70p \geq 300. Then we can solve by dividing both sides of the inequality by 70. We get p \geq 4.28... Since people only come in whole numbers, and it has to be greater than 4.28, the number of excess passengers is 5.

Hope this helped!

Do you need with the x value for the minimum? its always between the two intercepts for a parabola
