John and Mary were each paid x dollars in advance to do a certain job together. John worked on the job for 10 hours and Mary worked 4 hours less than John. If Mary gave John y dollars of her payment so that they would have received the same hourly wage, what was the dollar amount, in terms of y, that John was paid in advance?	Choose the correct choice from the following options: A) 4y B) 5y C) 6y D) 8y E) 9y
Let $x be the advance that both receive = 4x   Amount earned per hour by John and Mary = x/10 and x/6   Mary gives $y to John to make the wages earned equal   Hence John wage per hr = (x+y)10 which is now equal to Mary's wage (x-y)/6   Solve (x+y)10 = (x-y)/6   6x + 6y = 10x -10y   4x = 16y   x = 4y   Ans. 4y
