Solving the Mystery of Santiago's Chores

In this article, we will delve into the world of mathematics and solve a real-life problem involving hourly wages and total earnings. Santiago, a diligent individual, earns ${$ $3$}$ per hour for completing his chores. This weekend, he worked on both Saturday and Sunday, earning a total of ${$ $21$}$. We will use mathematical concepts to determine the number of hours Santiago spent doing chores on Sunday.

Santiago earns ${$ $3$}$ per hour for his chores. On Saturday, he worked for 4 hours, which means he earned ${$ $3$}$ x 4 = ${$ $12$}$ for that day. Since he earned a total of ${$ $21$}$ for the weekend, we can calculate the amount he earned on Sunday by subtracting the amount earned on Saturday from the total earnings.

Calculating the Earnings on Sunday

To find out how much Santiago earned on Sunday, we subtract the amount earned on Saturday from the total earnings:

${$ $21$}$ (total earnings) - ${$ $12$}$ (earnings on Saturday) = ${$ $9$}$ (earnings on Sunday)

Determining the Number of Hours Worked on Sunday

Now that we know Santiago earned ${$ $9$}$ on Sunday, we can use the hourly wage to determine the number of hours he worked. Since he earns ${$ $3$}$ per hour, we can divide the earnings on Sunday by the hourly wage to find the number of hours worked:

${$ $9$}$ (earnings on Sunday) ÷ ${$ $3$}$ (hourly wage) = 3 hours

In conclusion, Santiago worked for 3 hours on Sunday, earning a total of ${$ $9$}$. This problem demonstrates the application of mathematical concepts, such as hourly wages and total earnings, to solve real-life problems.

If Santiago's hourly wage changes, we can recalculate the number of hours worked on Sunday using the new hourly wage.
If the total earnings for the weekend change, we can recalculate the number of hours worked on Sunday using the new total earnings.
This problem can be extended to involve multiple days, multiple people, or different hourly wages.

This problem has real-world applications in various fields, such as:

Finance: Understanding hourly wages and total earnings is crucial in finance, where individuals need to manage their income and expenses.
Business: Calculating hourly wages and total earnings is essential in business, where companies need to determine employee salaries and benefits.
