A trip out west will cost $1075 in total airfare plus an average of $450 per day in expenses. A trip south will cost $1500 in total airfare plus an average of $365 per day in expenses, How many days whould they stay so that a trip south is cheaper than a trip west?
Let n be the total number of days. Then the cost& of trip west is equal to $1075 + n * $450,
while the cost of trip south is $1500 + n*$365.
We should have n such that 1075 + 450 n> 1500 + 365 n 85 n >& 425 & n > 5
