A parking garage opens at 8 AM. The graph shows the total number of cars in the garage. How many cars were parked in the garage overnight? A.30 B.20 C.40 D.60

Answer:
D, 60.
Step-by-step explanation:
Well first of all, 30, 20, or 40 isn't even on the graph in the first place, and since the garage opens at 8, and it was 8 exactly and there were 60 cars parked, that means there was 60 parked over night. hope i helped!!
