89. The table above shows the concellation fee schedule that a travel agency
    uses to determine the fee charged to a tourist who cancels a trip prior
    to departure. If a tourist canceled a trip with a package price of $1700
    and a departure date of Sep. 4, on what day was the trip canceled?

    (1) The Cancellation fee was $595.
    (2) If the trip had been canceled one day later, the cancellation fee
        would have been $255 more.

Answer: C

我想要請問一下各位是否可以幫我說明一下為什麼是C
我看了後面OG的解釋..完全看不懂第二項的解釋
謝謝!
