OG C #220 John and Mary were each paid x dollars in advance [#permalink]

OG C #220 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 2 hrs 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 $ amount, in terms of y, htat John was paid in advance?

For example J and M recieve 1 $ per hour If they worked equal numbers of hours than J has 9 $ and M has 9 $ But scince J worked 10 hours and M 8 hours than J has 10 $ and M has y (1 $) less because she gave it to J (9-1=8 $) Therefore, the given y to J (1 $ ) is 1/9 of the sum that J received in advance and tharefore, the aswer is 9y. what is OA?

hourly wage of Jonh =x/10 hourly wage of Mary =x/8

x/10 + y = x/8 -y , so x =80y, in term of y, John paid 80y, correct? _________________

IMHO I think we can not see their wages as you showed above because according to the stem they receive equal amount of money and therefore their wages must be equal at the begining.

Yeah, x is equal amount they each receive at the beginning. Due to their working hours different, hourly wage of them is different. x/10 and x/8 _________________
