Final answer:
After calculating Sally's expenses for the airline ticket and the hotel stay, Sally has $260 remaining from her initial savings of $600.
Step-by-step explanation:
The question involves calculating the remaining amount of money Sally has after spending on an airline ticket and hotel accommodation. Initially, Sally saves $600. She then spends $120 on an airline ticket. The cost of the hotel for 4 nights is $55 per night, amounting to a total hotel cost of $55 x 4 = $220. To determine the money Sally has left, we subtract the sum of her expenditures from her initial savings:
Total amount left = Initial savings - (Airline ticket + Hotel cost)
Total amount left = $600 - ($120 + $220)
Total amount left = $600 - $340
Total amount left = $260
Sally has $260 remaining after her expenses.
