Carla works 5 ½ hours and earns $52. 25. If Anthony makes an hourly rate that is proportional and earns $71.25, how many hours did he work?

a) 2 b) 7 ½ c) 9 ½ d) 13

Answer 1

The answer is B. If you put the information given into a proportion, you will find that Anthony worked for 7.5 hours. When the problem says that his hourly rate is proportional to Carla's, it means that he gets the same amount of money per hour as she does.
