Answer 1

Step 1: Define the Variable
Let x be the weight of the sixth person.

Step 2: Write the Inequality
The inequality is 780 + x ≤ 950.

Step 3: Solve (using Inverse Operations)
Subtract 780 from both sides of the inequality:
780 + x - 780 ≤ 950 - 780
x ≤ 170

Step 4: Check
The maximum weight the sixth person can weigh is 170 pounds.

Step 5: Answer in a Sentence
To ride the elevator safely, the maximum weight the sixth person can weigh is 170 pounds.
