Samantha went to a bike store to purchase a new bike.
The store was having a sale. If the total purchase, not
including tax was over $200, you got 25% off your
purchase. And, if your total was over $250, you got 30%
off your purchase. Samuel picked out a bike for $189,
two t-shirts for $28 each, and a water bottle for $5.50.
What was his total purchase price before tax?
