Final answer:
To calculate the break-even point for a season ski pass versus daily passes, set up a linear equation to compare the costs, subtract the constants, and solve for the number of days where the season pass becomes less expensive.
Step-by-step explanation:
The subject's question pertains to cost comparison and finding the break-even point between purchasing daily ski passes versus a season ski pass. While specific dollar values were omitted, the general approach to solving this type of problem involves setting up a linear equation where the total cost of daily passes equals the cost of the season pass plus rental fees. To illustrate the process, let's assume D represents the cost of a daily pass, S is the cost of the season pass, and R is the daily rental fee for skis. If x represents the number of days the skier plans to ski, the equation is Dx + Rx = S + Rx. Since rental fees are the same on both sides, they cancel out, and we're left with Dx = S. To find the break-even point, you solve for x by dividing S by D: x = S / D. The number of days the skier needs to ski for the season pass to be more economical is when x is greater than the result of S / D.
