A copy machine repairman makes $12.50 per hour plus $4 for every service call he performs. Last week he worked 34 hours and made 6 service calls. How much money did he make?

  1. $449

  2. $334

  3. $428

  4. $375

The correct answer is: $449

To determine the total earnings of the copy machine repairman, you need to calculate both the hourly wage and the additional earnings from service calls. First, calculate the total earnings from the hours worked. The repairman worked 34 hours, and at a rate of $12.50 per hour, this amounts to: 34 hours × $12.50/hour = $425. Next, calculate the earnings from the service calls. The repairman made 6 service calls and earns an additional $4 for each call. Therefore, the total earnings from service calls are: 6 calls × $4/call = $24. Now, combine the earnings from both sources to find the total earnings: Total earnings = Earnings from hours worked + Earnings from service calls Total earnings = $425 + $24 = $449. Thus, the repairman made a total of $449 last week.
