Answer: 10.50x ≤ 205 The maximum number of tickets, x, would be 19. Step-by-step explanation: Given, The cost of one ticket = $ 10.50, The cost of x tickets = 10.50x dollars, Since, the total cost can not exceed $ 205, ⇒ 10.50x ≤ 205 ∵ 10.50 > 0 thus, when we multiply both sides by 1/10.50 the inequality sign will not change, ⇒ x ≤ ≈ 19.52 Hence, the maximum number of tickets would be 19.
