An owner of a repair service company estimates that for every 30 hours a repairperson is on the job, he can bill for only 83% of the hours. For the remaining hours, the repairperson is idle or driving to or from a job. Determine the number of hours per 30-hour week the owner can bill for a repairperson
The number of hours per 30-hour week the owner can bill for a repairperson is?

6/ 11 = 0.545454 so your answer is55%

The answer is 270 cars.you can do this by making a proportional relationship. for instance, 200 is the whole we are using, so on a “number line” 200 would be over 100%. now, since he sells 35% more, add 35% to 100% to get 135% on the other side of the “number line” on the bottom half, leaving the top half empty.cross multiply 200 by 135 then divide by 100 to get your answer. i hope this , if it did, , if you don’t mind, giving me brainiest! 200/100% } 200 • 135 /100 ? /135%
