April's Challenge

The students in Mr. Martin’s third hour geometry class have been acting rather weird lately. After class on Tuesday he found the following secret message written on a crumpled up piece of paper.

X4D5P2P4D4D0X3X1 P0X3P2P4P9 D2K4K7
K2X3K7P4D5K3 K4K3 D2P2D5X6X3P9!

As he was leaving that day he discovered a scrap of paper on the floor. It was a similar message with a helpful clue:

P4D1P3K9 = TEST

Decode the original message.

Solution: Birthday party for Martin on Friday!
