Toni and Morris go to a department store to buy some shirts. Customers must pay full price for the first shirt each
buys, but they receive a 40% discount on the second shirt they purchase, and a 60% discount on every shirt they
purchase beyond the second. Toni buys 4 shirts while Morris buys 3 shirts, and Toni pays $6.56 more for her
purchase than Morris pays for his. What was the original price of the shirt? (Assume there is no sales tax.)
