Mary and John were each paid x dollars in advance to do a certain job. ( I say let's make x- $100) John worked on the job for 10 hours and Mary worked for 8 hours. If Mary gave John y dollars of her payment so that they would have received the same hourly wage, what was the dollar amoung John was paid in advance?
100 + y
----- = 100 - y/ 8?
Is this right,
