a kier is trying to decide wheather or not to buy a season ski pass. A daily pass costs $76. A season ski pass costs $300. The skier would have rent skies with either pass for $20 per day. How many days would the skier have to go skiing in order to make the season pass less expensive than the daily passes?
Answer provided by our tutors
let d = the number of days skiing
d(76 + 20) >= 300 + 20d
by solving we find
d >= 3.95
