Sarah and Tom went to a store to buy some items. Sarah bought 2.5 times as many items as Tom did. Together, they bought 28 items. If the total cost of their items was $195.60, and each item cost $7.20, how many items did each of them buy?

Let T be the number of items Tom bought.

Sarah bought 2.5 * T = 2.5T items.
Tom and Sarah bought T + 2.5T = 28 items.
3.5T = 28
T = 28 / 3.5 = <<28/3.5=8>>8 items
Sarah bought 2.5 * 8 = <<2.5*8=20>>20 items.
Tom bought 8 items and Sarah bought 20 items. Answer: \boxed{8, 20}.
