Introduction

Eric's earnings are directly proportional to the number of hours he works. In this article, we will explore how to calculate Eric's earnings for a given number of hours worked, using the concept of rate and proportion.

Understanding the Problem

Eric made $180 for 9 hours of work. We need to find out how much he would make for 18 hours of work at the same rate.

Calculating Eric's Rate

To calculate Eric's rate, we need to divide his earnings by the number of hours he worked.

Rate = Earnings / Hours
Rate = $180 / 9 hours
Rate = $20 per hour

Applying the Rate to 18 Hours of Work

Now that we know Eric's rate, we can apply it to 18 hours of work to find his earnings.

Earnings = Rate x Hours
Earnings = $20 per hour x 18 hours
Earnings = $360

Conclusion

In this article, we calculated Eric's earnings for 18 hours of work using the concept of rate and proportion. By understanding the relationship between Eric's earnings and the number of hours he works, we were able to apply his rate to a different number of hours to find his new earnings.

Real-World Applications

This concept of rate and proportion has many real-world applications, such as:

Calculating the cost of goods sold in a business
Determining the amount of money earned from a part-time job
Understanding the relationship between the number of hours worked and the amount of money earned

Tips and Tricks

When calculating rates, make sure to use the correct units (e.g., dollars per hour, miles per gallon)
When applying rates to different numbers of hours, make sure to use the correct units and perform the correct calculations
Practice, practice, practice! The more you practice calculating rates and proportions, the more comfortable you will become with the concept.

Introduction

In our previous article, we explored how to calculate Eric's earnings for 18 hours of work using the concept of rate and proportion. In this article, we will answer some frequently asked questions about Eric's earnings and provide additional guidance on how to apply the concept of rate and proportion in real-world scenarios.

Q&A

Q: What is Eric's rate of pay?

A: Eric's rate of pay is $20 per hour.

Q: How did you calculate Eric's rate of pay?

A: We calculated Eric's rate of pay by dividing his earnings by the number of hours he worked. In this case, Eric made $180 for 9 hours of work, so his rate of pay is $180 / 9 hours = $20 per hour.

Q: How much would Eric make for 24 hours of work?

A: To calculate Eric's earnings for 24 hours of work, we can multiply his rate of pay by the number of hours he works. In this case, Eric's earnings would be $20 per hour x 24 hours = $480.

Q: What if Eric's rate of pay changes?

A: If Eric's rate of pay changes, we would need to recalculate his earnings using the new rate of pay. For example, if Eric's new rate of pay is $25 per hour, his earnings for 24 hours of work would be $25 per hour x 24 hours = $600.

Q: Can I use this concept to calculate my own earnings?

A: Yes, you can use this concept to calculate your own earnings. Simply divide your earnings by the number of hours you work to find your rate of pay, and then multiply your rate of pay by the number of hours you work to find your total earnings.

Q: What if I work different hours on different days?

A: If you work different hours on different days, you can calculate your earnings for each day separately and then add them up to find your total earnings. For example, if you work 8 hours on Monday and 10 hours on Tuesday, your earnings for the week would be $20 per hour x 8 hours + $20 per hour x 10 hours = $160 + $200 = $360.

Q: Can I use this concept to calculate my earnings for a part-time job?

A: Yes, you can use this concept to calculate your earnings for a part-time job. Simply divide your earnings by the number of hours you work to find your rate of pay, and then multiply your rate of pay by the number of hours you work to find your total earnings.

Conclusion

In this article, we answered some frequently asked questions about Eric's earnings and provided additional guidance on how to apply the concept of rate and proportion in real-world scenarios. By understanding the relationship between earnings and hours worked, you can make informed decisions about your finances and make the most of your time.
