Answer:
5 nights or less
Explanation:
You can do this by writing an inequality and solving it.
Let n = number of nights.
1 hotel night costs $60. n number of hotel nights cost 60n.
The flight costs $150.
The total cost is the price of the hotel plus the price of the flight.
60n + 150
The total price must be less than or equal to $500.
Now we solve the inequality.
Subtract 150 from both sides.
Divide both sides by 60.
350 divided by 60 is 5.8333...
The number of night is less than or equal to 5.8, and it must be a whole number, so the most number of nights she can afford is 5.
