Step-by-step explanation:

Given  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 740 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.

Given P represent the number of excess passengers .

Also the elevator cannot lift more than 450 kg.

According to question we have

740 – 70 P < 450  

Subtract 740 to both sides.

So 740 – 70 P – 740 < 450 – 740

-70 P < - 290

So P >29/7

The inequality sign is reversed when multiplied by negative number.

Therefore the inequality is P > 4, 14 or P > 29/7

The inequality would be: 620-37.4q is less than or equal to 450

and she needs 5 packages
