Modelling 3- digit numbers

To find different ways to buy 200 stamps using booklets of 100, 50, and 10, we can use a systematic approach. Let's create a chart to keep track of the different combinations:

| Booklet of 100 | Booklet of 50 | Booklet of 10 |
|--------------|-------------|--------------|
| | | |

We'll start by considering the booklet of 100. Since we need to buy 200 stamps, the maximum number of booklets of 100 we can get is 2.

1. Option 1: 2 booklets of 100 stamps
| Booklet of 100 | Booklet of 50 | Booklet of 10 |
|--------------|-------------|--------------|
| 2 | 0 | 0 |

Next, let's explore the possibilities using the booklet of 50 stamps.

2. Option 2: 1 booklet of 50 stamps
To make up for the remaining 150 stamps, we need to consider combinations using the booklet of 10 stamps. Since we can have a maximum of 1 booklet of 50, the maximum number of booklets of 10 we can have is 15.

For each possibility, let's record the number of booklets of 10 in the chart:

| Booklet of 100 | Booklet of 50 | Booklet of 10 |
|--------------|-------------|--------------|
| 2 | 1 | Variable |

We'll fill the chart table by trying different values for the variable:

2.1 Option 2.1: 1 booklet of 50 stamps, 0 booklets of 10
| Booklet of 100 | Booklet of 50 | Booklet of 10 |
|--------------|-------------|--------------|
| 2 | 1 | 0 |

2.2 Option 2.2: 1 booklet of 50 stamps, 1 booklet of 10
| Booklet of 100 | Booklet of 50 | Booklet of 10 |
|--------------|-------------|--------------|
| 2 | 1 | 1 |

2.3 Option 2.3: 1 booklet of 50 stamps, 2 booklets of 10
| Booklet of 100 | Booklet of 50 | Booklet of 10 |
|--------------|-------------|--------------|
| 2 | 1 | 2 |

Continue this process until you have considered all possibilities for the booklet of 50 stamps.

Now, let's explore the possibilities using the booklet of 10 stamps.

3. Option 3: Only booklets of 10 stamps
To buy 200 stamps using only the booklet of 10, we can have a maximum of 20 booklets:

| Booklet of 100 | Booklet of 50 | Booklet of 10 |
|--------------|-------------|--------------|
| 2 | 0 | Variable |

We'll fill the chart table by trying different values for the variable:

3.1 Option 3.1: 20 booklets of 10 stamps
| Booklet of 100 | Booklet of 50 | Booklet of 10 |
|--------------|-------------|--------------|
| 2 | 0 | 20 |

Now, let's summarize the different ways to buy 200 stamps:

1. 2 booklets of 100 stamps
2. 1 booklet of 50 stamps
- 0 booklets of 10 stamps
- 1 booklet of 10 stamps
- 2 booklets of 10 stamps
3. Only booklets of 10 stamps
- 20 booklets of 10 stamps

Throughout this process, we filled out the chart, considering different combinations using each booklet size.
