In this article, we will explore how to calculate the average weekly spending of an individual based on their expenses over a specific period.

The Problem

Let's consider the scenario of João, who had a spending on snacks in January in the first 3 weeks of R $ 48.50, R $ 78.00, and R $ 65.20. To find the average weekly spending, we need to calculate the total spending over the 3 weeks and then divide it by the number of weeks.

Calculating Total Spending

To calculate the total spending, we need to add up the expenses for each week.

Week 1: R $ 48.50
Week 2: R $ 78.00
Week 3: R $ 65.20

Total spending = R $ 48.50 + R $ 78.00 + R $ 65.20 Total spending = R $ 191.70

Calculating Average Weekly Spending

Now that we have the total spending, we can calculate the average weekly spending by dividing the total spending by the number of weeks.

Average weekly spending = Total spending / Number of weeks Average weekly spending = R $ 191.70 / 3 Average weekly spending = R $ 63.90

Conclusion

In conclusion, by following the steps outlined in this article, we can calculate the average weekly spending of an individual based on their expenses over a specific period. In the case of João, his average weekly spending on snacks in January was R $ 63.90.
