Explanation / Answer
She buys her first 10 ink cartridges at regular price, and the rest she can purchase for 10% off - because if when she buys 0, she has paid 0 - crosses both x axis and y axis. For the first two: She buys a discount card so that she gets a free ink cartridge for every five that she buys and She pays an initial fee for a lifetime of ink cartridges at half-price, she has spent money without buying any cartridges, so she is already above the x-axis to start and will just continue upward. For the third, She gets her first two ink cartridges for free, she gets 2 free, never goes below 2, so never hits the y-axis.
