Antoine went on vacation to Las Vegas. His room cost $115.62 each night. His flight there cost $45.70 and his flight home was $32.49. He averaged $15.00 per day on food. On the first day Antoine won $75.00 and on the last day he lost $25.00. If he stayed for 3 months and 4 days, how much did the entire trip (including airfare, food, hotel, and winnings) cost him?

Respuesta :

lets calculate expenses step by step:
room = (3*30 + 4)*115.62 = 10868.28, those are the total days multiplied by the room cost
flight = 45.70 + 32.49 = 78.19
food = (3*30 + 4)*15 = 1410
win = 75
lost = 25
so the total is:
total = room + flight + food + lost - win
= 12306.47
that is the cost of the entire trip, note how we subtracted the win from all other expenses
