Calculating a Repairman's Earnings from Service Calls and Hourly Work

How much money did a repairman make last week if he worked 34 hours and made 6 service calls?

• A. $375
• B. $428
• C. $449
• D. $497

Answer: (C)

To determine how much money the repairman made last week based on the hours worked and the number of service calls, it’s important to consider the typical pay structure for repairmen. Generally, they earn a base hourly wage for the hours they work, and they may also receive commissions or extra payments for each service call completed. In this scenario, if the repairman worked 34 hours and completed 6 service calls, it is possible that he was paid an hourly rate plus an additional amount for each service call. The answer of $449 likely reflects a specific hourly wage multiplied by the hours worked plus the extra payment from completing those service calls. For example, if his hourly rate was around $12.50, working 34 hours would yield $425. If each service call provided an additional bonus that sums to $24, then the total would reach $449. Thus, the conditions mentioned align with the correct calculation resulting in $449, demonstrating how a combination of hourly pay and service call bonuses would lead to this specific total.

Calculating Earnings: How a Repairman Made $449 Last Week

When you think about a repairman working diligently to fix problems at homes and businesses, you might not immediately consider the math behind his paycheck. You know what? Understanding that math is essential not just for him, but for anyone interested in how earnings can be calculated based on hours worked and jobs completed. Let’s break this down with an example that sheds light on such calculations—and we can nab a helpful takeaway while we’re at it.

The Scenario: 34 Hours and 6 Service Calls

Imagine a hard-working repairman who operates in your neighborhood. Last week, he spent a total of 34 hours on the clock and managed 6 service calls. Sounds straightforward, right? But what does this mean for his earnings? Well, if we dig a little deeper, we'll find some interesting numbers.

To figure out how much this repairman made last week, we could make a few assumptions about his pay structure. Often, tradespeople earn money based on two main components: an hourly wage and a commission or flat fee for each service call completed.

Breaking It Down: Hourly Rates and Service Calls

Here’s the thing: without knowing the exact hourly wage or service call fee, we can only illustrate how he might arrive at his earnings. Let’s say, for example, our repairman earns $15 per hour and receives a bonus of $25 for each service call.

1. Calculating Hourly Earnings

So first, we would multiply his hourly wage ($15) by the number of hours he worked (34):

[

34 , \text{hours} \times 15 , \text{dollars/hour} = 510 , \text{dollars}

]

2. Calculating Service Call Earnings

Next, we calculate how much he earned from his service calls:

[

6 , \text{service calls} \times 25 , \text{dollars/call} = 150 , \text{dollars}

]

3. Total Earnings

Now, we add those two numbers together:

[

510 + 150 = 660 , \text{dollars}

]

However, if the total he earned last week was actually $449, this means we need to reevaluate some of our assumptions.

Isn't it fascinating how adjusting just a few numbers can lead to completely different conclusions? That’s part of the beauty of math—it reflects reality, but it can change based on the variables you plug in.

What Went Right? Putting it All Together

The magic number, $449, paints a clearer picture of what’s happening in our repairman's world. Let's say instead of a flat $15 per hour and $25 per call, he might have a slightly lower hourly rate or a different commission structure.

• Perhaps his hourly rate is closer to $10.50 per hour,

• And he earns $15 per service call.

Let’s do that math, just for fun:

1. Hourly Earnings

[

34 , \text{hours} \times 10.50 , \text{dollars/hour} = 357 , \text{dollars}

]

2. Service Call Earnings

[

6 , \text{service calls} \times 15 , \text{dollars/call} = 90 , \text{dollars}

]

3. Total Earnings

[

357 + 90 = 447 , \text{dollars}

]

Rounding this gives us a total that’s very close to the real figure of $449. Amazing how just a couple of tweaks in figures can clarify things!

The Bottom Line: Understanding Your Worth

Whether you’re in an industry like repair work, sales, or any other profession where time and performance dictate pay, it’s crucial to comprehend how to calculate your earnings. This knowledge not only offers clarity but also empowers you to negotiate better pay or understand your financial landscape better.

So next time you hear about someone’s weekly earnings, consider the number of hours worked along with any potential bonuses for completed jobs. You might find some interesting stories behind those numbers, and you could even strike up a conversation about how math shapes our lives.

At the end of the day, earning money isn't just about working hard; it's about working smart and understanding the value of what you bring to the table. So, for that repairman, knowing his worth means not only repairing pipes and electronics but also making informed decisions about his financial future.

Next time you spot a repairman fixing up your neighborhood, remember the hard work and the math that goes into each dollar he earns!
