Bunny Hill Ski Resort charges $35 for ski rental and $10 an hour to ski. Black Diamond Ski Resort charges $40 for ski rental and $5 an hour to ski. Create an equation to determine at what point the cost of both ski slopes is the same.
 HELP PLZZZZZZZZZ :(
 A 10x − 35 = 5x − 40
 B 10x + 35 = 5x + 40
 C 10x + 40 = 5x + 35
 D 10x − 40 = 5x − 35
