Question: Rebecca bought 22 items for her camping trip, including tent stakes, packets of drink mix, and bottles of water. She bought 3 times as many packets of drink mix as tent stakes. She also bought 2 more bottles of water than she did tent stakes. How many tent stakes did she buy? Think carefully first, then make a decision:

Let x represent the number of tent stakes. Drink Mix: 3x. Bottles of Water: x + 2. Total: x + 3x + x + 2 = 22. 5x + 2 = 22. 5x = 20. x = 4 tent stakes. So the answer is 4.
