A memory chip is being designed to hold a number of transistors and heat sinks. The transistors hold memory while the heat sinks cool the chip. There must be at least one heat sink for every transistors to prevent overheating. Also, each transistor has an area of (square millimeters), each heat sink has an area of , and the total area of transistors and heat sinks must be at most . What is the approximate maximum number of transistors that the chip can hold according to this design?
