4. A coffee shop currently sells 480 lattes a day at $3.00 each. They recently tried raising the price and found
that they sell 60 less lattes a day for each $0.60 increase in the price. Let x represent the number of $0.60
increases in the price of a latte. Write a function in the variable x that represents the daily revenue from
selling lattes and determine the domain of the function. Hint: Revenue = (price per latte) (no. of lattes sold)
