Step-by-step explanation: We want to find the rate that we have to pay the daycare for each hour. This rate does not include the initial 10 dollar fee, but the total charges do, so you begin by subtracting 10 from 31.25, which gives you how much you paid in total for the hourly fees. And since you had to pay for 8.5 hours, you divide 21.25 by 8.5, to get the hourly fee for the daycare, which is; 2.50.
First subtract the cost of pickup from the total cost 31.25-10= 21.25 now you want to determine the cost per hour so divide 21.25 by 8.5 to find you final answer. They charge $2.50 per hour
