A. Write the equation for the expenses: Total expenses = $15 per night. number of nights + $600

Y=15x+600

Y=15x + 600

Step-by-step explanation:

The total expenses depend on the fixed cost plus the number of nights spent and the cost per night.

The cost per night is $15 hence for x number of nights, expenses for nights only is 15x. Additionally, we add the fixed cost of $600 to get the total expenses hence the equation becomes

Y=15x+600
