The student decides that the tennis rackets and the towels are needed. How does
this affect the inequality in part (a)?

Answer 1

The inequality that represents this situation is x ≤ 6. On the other hand, the parents can ship only the tennis rackets.

What equality represents this situation?

The equality that represents this situation is x ≤ 6 because the number of pounds that can be added (x) has to be 6 or less than 6.

What other item can they ship?

The parents can only ship the tennis rackets because these are 5 pounds which meets the criteria of the inequality.

What happens if the student needs the towels and the tennis racket?

The inequality would change to x ≤ 1 because the weight that could be added if he needs these producs changes to only 1 pound.
