    A skier is trying to decide whether or not to buy a season ski pass. A daily pass costs $75. A season ski pass costs $350. The skier would have to rent skis 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?

    Let d be the number of days:

    Daily Plan cost: 75d + 20d = 95d
    Season Pass: 350 + 20d

    We want to find d such that
    350 + 20d < 95d

    Subtract 20d from each side
    75d > 350

    Divide each side by 75
    d > 4.66667
    d = 5
