Two-step inequality word problems

Renna pushed the button for the elevator to go up, but it would not move. The weight limit for the elevator is 450450 kilograms, but the current group of passengers weighs a total of 750750 kilograms. Renna wants to determine how many 7070-kilogram passengers need to get off the elevator.
Let pp 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 who need to get off the elevator to meet the weight requirement?
