Final answer:
To find the number of golfers at the point of indifference between two golf courses, one must equate the total cost equations of hosting the golf outing at each course and solve for the number of golfers.
Step-by-step explanation:
The point of indifference is when the total cost for hosting the golf outing at both golf courses is the same. The total cost for each option can be expressed by a cost-equation that includes both the fixed and variable costs. For Kissena Park Golf Course (Option 1), the equation is C1 = $5,000 + $30x, where C1 is the total cost and x is the number of golfers. For Clearview Golf Course (Option 2), the equation is C2 = $4,000 + $35x. To find the point of indifference, we can set the two equations equal to each other because at that point, C1 = C2: $5,000 + $30x = $4,000 + $35x. Solving for x will give the number of golfers at the point of indifference.
