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. What is the minimum whole number of passengers that need to get off the elevator?

Excess weight = 750 - 450 = 300kg
No of people to get off from the elevator with 70kg = 300 ÷ 70 = 4.29
ie. minimum 5 people need to get off from elevator.
