Yes, the total cost of Lacey lesson is a split function of hours scheduled
Step-by-step explanation:
The amount Lacey pays for each hour of golf = $15
The amount Lacey pays for equipment rental = $10
The amount Lacy pays for equipment rental for a 3 hours long lesson = $5
Therefore, we have

C = $10 + t × $15 for 0 ≤ t ≤ 3
C = $5 + t × $15 for t > 3
Therefore, the total cost of Lacey lesson is a split function of hours scheduled
