Answer:
[tex]200+48n\leq 3500[/tex]
[tex]n\leq 66.7[/tex]
Step-by-step explanation:
Let the number of cartons he can safely put on the elevator at one time=n
Total weight of Carton=48n
Since the weight of the man and the cartons combined must not be more than 3500 pounds,
Therefore,an inequality that represents the situation is:
[tex]200+48n\leq 3500[/tex]
We can solve for n if required
[tex]200-200+48n\leq 3500-200\\48n\leq 3200\\\text{Divide both sides by 48}\\n\leq66.7[/tex]
The delivery man can safely carry 66 Cartons.
