Shiloh wants to buy a long lasting candle. Type 1 candle melts by 19.5 cm each hour. Type 2 candle melts by 0.15 inch each minute. Both the candles have the same original height.

[1 inch = 2.54 cm]

Part A: Which type of candle should Shiloh buy? Justify your answer by comparing the rate at which they melt after converting to the same units. (5 points)

Part B: If the original height of the candles was 40 cm and you checked on its height every 30 minutes after lighting it, describe appropriate scales on the x-axis and y-axis to graph the rate at which the slower candle melts. (5 points)
