Given the data, the following equation can be made...
60+30x=390 where x is the number of hours the fix-it man worked
60+30x=390
subtract 60 from both sides
30x=330
divide both sides by 30
x=11 hours
Answer=11 hours
60+30x=390 where x is the number of hours the fix-it man worked
60+30x=390
subtract 60 from both sides
30x=330
divide both sides by 30
x=11 hours
Answer=11 hours
Since it's 60 for him to come, subtract 60. So then it is 30 dollars per hour and he paid 330. To find the unit rate, divide 330 by 30, which is 11, so the fix-it man worked 11 hours.
