Please help please please

Answer:The top-left box should be 4x, and the bottom-left box should be 2.50x.Step-by-step explanation:Because the cost from 2 hours to 6 hours is 4 dollars per hour, it is 4x. Likewise, because the cost over 6 hours is 2.50 dollars per hour, the cost is 2.50x. Everything else seems fine.Hope this helps!
