if she spent 16 dollars, and each cost the same, these are the possiblieties of how many she could've bought (and for how much)
sixteen t-shirts for a dollar each eight t-shirts for two dollars each four t-shirts for four (tongue twister :) ) dollars each two t-shirts for eight dollars a piece and one t-shirt for sixteen dollars
Jean could buy T-shirts in different quantities depending on their price. She could buy 16 T-shirts at $1 each, 8 at $2 each, 4 at $4 each, 2 at $8 each, or 1 at $16. The key is that the cost per shirt must be a whole number that divides evenly into $16.
