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?
Use reasoning to answer the following question.
4
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 final answer is 4
