Harold had $20 to spend. He decided buy a shirt for $15.95. Spend the rest on packs of gum if each pack of gum costs $1.99 how many packs of gum can Harold buy

First, we need to calculate how much money Harold will have left after buying the shirt:

$20 - $15.95 = $4.05

Now we can calculate how many packs of gum Harold can buy with that money:
$4.05 / $1.99 ≈ 2

Harold can buy 2 packs of gum with the money he has left after buying the shirt.
