$2.50 x 6 = $15.00
$1.25 x 1 = $ 1.25
$0.50 x 2 = $ 1.00 ... total: $17.25
==========================================
Now...
6 x 12 cards = 72 cards
3 x 1 card = 3 cards
2 x 2 cards = 4 cards ... total: 79 cards

Total = 2.50 + 1.25 + .50 = 4.25
17.25 times 4.25 = 73.3125
If we round that decimal to the ones place, we get 73.
