Step-by-step reasoning process: Sam makes $460 / 23 hrs = $20 / hr. From September to February, Sam made 8hrs x $20 / hr = $160. From March to February, Sam made a total of $460 + $160 = $620. After fixing his car, he was left with $620 - $340 = $280. Sam needs another $600 - $280 = $320. Sam needs to work another $320 / $20 / hr = 16 hours.
The question and answer:
Question and answer:
From March to August, Sam made $460 doing 23 hours of yard work. However, from September to February, Sam was only able to work for 8 hours.
