Thanks! we know that both J and M worked a total of 18 hours They each got paid x dollars. Total money paid out therefore is 2x therefore the hourly wage is 2x/18 = x/9 now John worked 10 hours, but got paid x (for 9 hours), so Mary paid him y for the extra 1 hour to equilise their payments therefore x/9 = y . Hence x=9y and x is what John got paid. E

How did you come up with 9 hours -- now John worked 10 hours, but got paid x (for 9 hours),
Thanks for your input.

Thanks for your input. basically the stem says that John worked for 10 hours out of a total of 18. So Mary worked for 8. BUT they both got paid evenly. Mary (because she is so nice  ) decide to give John some money to equalise their pay so if she gives John 1 hour's worth of pay, since he has been paid 9 hours worth in advanced ($x), this will equalise the pay. sorry if I was unclear in my original post

Let $x be the advance that both receive = 2x
Amount earned per hour by John and Mary = x/10 and x/8
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)/8
Solve (x+y)10 = (x-y)/8
8x + 8y = 10x -10y
2x = 18y
x = 9y
Ans. E

Have anyone of you tried to solve this problem MGMAT way. That is, by substituting #'s

The way I figured it was substituting numbers. John works 10 hours, Mary 8. So total of 18 hours. I did this. They each get $90, so total of $180. That's $9 / hr for john and $11.25 for Mary. It's easier to figure out with $180 and 18 hours, they should each get $10 / hr. So if John has $90 and needs $100 to give him $10/hr, then Mary gives him $10, which is y. The question says "In terms of y, how much did John get to begin with?" Well that's \frac{90}{10}yvksunder wrote: Have anyone of you tried to solve this problem MGMAT way.

Thanks! suppose they get paid $80 each.. John's hourly wage is $8/hour Mary's hourly wage is $80/8=$10/hour.. she must give john $1/hour or $10.. so if y=$10..then Johns total $90.. thus in terms of y..John gets 9y

I dont understand how you guyz got 9. My approach is; x/10 johns wage x/8 mary wage x/8-y=x/10+y x= 80y 80y/10= 8y so my answer was D however it is wrong. I dont get it
