Now she/he needs to buy more thank you cards as many she can get so Subtract it (2.99) 4 times then you get your answer Like this (12.35-2.99=9.36) (9.36-2.99=6.37) (6.37-2.99=3.38) (3.38-2.99=0.39) now after that she can’t buy no more so after that, I subtracted 4 times so basically the answer is 4 thank you cards that she bought
