Learning Task 1

An old woman is overweight. Her doctor told her to decrease by 35 kilos. She lost:

- 11 kilos in the 1st week
- 9 kilos in the 2nd week
- 7 kilos in the 3rd week

If she continues losing weight at this rate, how long will it take her to lose 35 kilos? Fill out the table below to get the answer.

\[
\begin{tabular}{|c|c|c|c|c|c|}
\hline
\textbf{Week} & 1 & 2 & 3 & 4 & 5 \\
\hline
\textbf{Kilos} & 11 & 9 & 7 & 5 & 3 \\
\hline
\end{tabular}
\]

How did you get the answer?

Her weight reduced by 2 kilos every subsequent week.

Let's solve this problem step-by-step by tracking the cumulative weight loss week by week.

1. Week 1:
- Kilos lost: 11
- Total kilos lost so far: 11

After the first week, 11 kilos have been lost.

2. Week 2:
- Kilos lost: 9
- Total kilos lost so far: 11 + 9 = 20

After the second week, 20 kilos have been lost in total.

3. Week 3:
- Kilos lost: 7
- Total kilos lost so far: 20 + 7 = 27

After the third week, 27 kilos have been lost in total.

4. Week 4:
- Kilos lost: 5
- Total kilos lost so far: 27 + 5 = 32

After the fourth week, 32 kilos have been lost in total.

5. Week 5:
- Kilos lost: 3
- Total kilos lost so far: 32 + 3 = 35

After the fifth week, 35 kilos have been lost in total.

Now we can summarize the calculations in the following table:

[tex]\[
\begin{array}{|c|c|c|c|c|c|}
\hline \text{WEEK} & 1 & 2 & 3 & 4 & 5 \\
\hline \text{KILOS} & 11 & 9 & 7 & 5 & 3 \\
\hline
\end{array}
\][/tex]

### Conclusion:
The overweight woman will lose exactly 35 kilos in 5 weeks.

Her weight reduced by different kilos each week in the following order: 11, 9, 7, 5, and 3 respectively.
