I am very sure I am correct, because this was a subject in math I could highly understand, the answer the side you are asking for, B = 4
6:45pm. because from 4 to 12 would be 4 hours then subtract 5 more hours leaves you at 7:25 pm. now subtract 45 from that which leaves you at 6:45 pm.
22 X = Y
x = number of rooms cleaned
Y = cost
