Let's tally up the food that the thief stole:
-
From McDonald's:
- 2 Big Macs
- 4-piece chicken nuggets
Total from McDonald's: 2 Big Macs + 1 (4-piece chicken nugget) = 2 + 1 = 3 items
-
From the store:
- 4 barbeque steaks
- 2 bags of potato chips
Total from the store: 4 barbeque steaks + 2 bags of potato chips = 4 + 2 = 6 items
-
At night:
- 2 ham steaks
- 1 turkey sandwich
- 3 packs of gummy bears
Total at night: 2 ham steaks + 1 turkey sandwich + 3 packs of gummy bears = 2 + 1 + 3 = 6 items
Now, let's add all the items together:
- From McDonald's: 3 items
- From the store: 6 items
- At night: 6 items
Total food stolen: 3 + 6 + 6 = 15 items
Therefore, the crook stole a total of 15 items of food.
