Edited the question as there was a typo.
Range = Highest Value - Lowest Value.Range in May was 15,000 and the lowest price in May was 4,500, thus the highest price in May was 15,000+4,500=19,500.
Range in June was 16,500 and the lowest price in June was 6,100, thus the highest price in June was 16,500+6,100=22,600.
Lowest price of a car in May-June was 4,500 (May) and the highest price of a car in May-June was 22,600, thus the range for May-June is 22,600-4,500=18,100.
