Final answer:
Abdul can sell between 0 to 5 more tickets, as each ticket costs $7 and he has $35 worth of ticket sales remaining to reach the $140 limit.
Step-by-step explanation:
The student asks how many more tickets Abdul can sell if he has already sold $105 worth and cannot exceed $140 in total ticket sales. Tickets cost $7 each.
To determine the reasonable range of tickets Abdul can sell, we first find the remaining amount he can sell: $140 - $105 = $35. Then we divide the remaining amount by the price per ticket to find how many tickets can be sold: $35 ÷ $7 = 5 tickets. Abdul can sell up to 5 more tickets without exceeding the $140 limit.
Therefore, if Abdul has already sold $105 worth of tickets and each ticket costs $7, he can reasonably sell between 0 to 5 more tickets.
