A copy machine repairman makes $12.50 per hour plus $4 for every service call he performs. Last week he worked 34 hours and made 6 service calls. How much money did he make?
Hours = 34
Income per hour = 12.5$
Service calls = 6
Income per call = 4
Therefore, total income
= (time of working * income per hour) + (service calls * income per call) = (34*12.5) + (6*4)
= 425+24
= 449
