Assumptions: Car gets 20mpg, Dallas to Chicago is 2E3 miles, Ink cartrige is 20 ml and costs 25$, 2L is 1 gallonSchrodingerscat wrote: If cars were to run on the ink out of printer cartridges with the same "ink efficiency" as gas efficiency, how much would you spend on ink to drive from Dallas, TX to Chicago, IL?

Then it is simple multiplication and division, giving 2E3/20*2*1000/20*25 = 2.5E5

What is the 1,000,000th prime number? (This was on my regional test) If stuck, use prime number theorem.
