Answer:
27 Marbles
Step-by-step explanation:
Alan first had 5 marbles, and then <em>added</em> 4 to the collection.
5 + 4 = 9
He went to the store and tripled the number of marbles he had.
9 x 3 = 27
Hence, he now has 27 marbles.
The percent discount was,
55.5556. It could be changed to 56%, but as a whole it would more than likely be 55%.
