please tell me the steps to solve this! i seriously appreciate your help!!

The key to problems like these are to:

- Identify the
**elements**: dollars, wrappers, chocolates - Identify (and remember!) the
**goal**: changing dollars and wrappers into chocolates

You can write each **element** in terms of your goal (chocolate).

- dollars ($1 = 1 chocolate)
- sets of wrappers (3 wrappers = 1 chocolate)

Now work on the **goal** - change those dollars and wrappers into chocolate. After each calculation you make, check your balance - how many dollars and how many wrappers are left?

Balance: 15 dollars, 0 wrappers, 0 chocolates

- Change dollars into chocolate and wrappers
- Spend 15 dollars, Get 15 chocolates, 15 wrappers

New balance: 0 dollars, 15 wrappers, 15 chocolates

- Change wrappers into chocolates and wrappers
- Spend 15 wrappers, Get 5 chocolates and 5 wrappers

New balance: 0 dollars, 5 wrappers, 20 chocolates

- Change wrappers into chocolates and wrappers
- Spend 3 wrappers, Get 1 chocolate and 1 wrapper

New balance: 0 dollars, 3 wrappers, 21 chocolates

- Change wrappers into chocolates and wrappers
- Spend 3 wrappers, Get 1 chocolate and 1 wrapper

New balance: 0 dollars, 1 wrappers, 22 chocolates

Can you buy any more chocolates? Not with 0 dollars and less than 3 wrappers, so you know you're done!

**Final Answer: 22 chocolates**
