Answer: 5 nights
Explanation:
Let x represent the number of nights she wants to stay at the hotel during her holiday.
The hotel costs $60 per night and her flights cost $150. This means that the total amount of money that she would pay for her flight and x nights of staying at the hotel would be expressed as
60x + 150
She has a budget of $500 for hotel and flights. This means that
60x + 150 = 500
60x = 500 - 150
60x = 350
x = 350/60
x = 5.833
Since x cannot be a fraction, it means that she can only afford 5 nights in the hotel.
