Answer:
c = 10h
Step-by-step explanation:
c = 8h
Where,
c = Total amount she should charge a customer
h = Number of hours
8 = amount charged per hour of babysitting

B. If she decides to increase the rate she charges customers by $2 per hour, then the new equation she should use to determine how much to charge her customers is:
c = (8 + 2)h
c = 10h
