Answer:

The answer is d) 4d = 320 - 60 becasue d is the dollors he made per hour and the repairman worked for 4 hours so you multiply 4 times d and then you subtract 60 from the total to get your final answer. If you subtracted already then you would divide that answer by 4 then you would find out how much the repairman maid per hour.
