Ann's daily wage is $10 less that Bill's. So she has to work 4 days more than Bill to earn the same amount of money as Bill. If Bill earns $480, find Ann's daily wage.
I created a table like so,
Ann Bill
Wage (x-10) x
Days (y+4) y
Salary (x-10)(y+4) 480
Then, using the equation,
(x-10)(y+4) = 480
I got,
2x - 5y = 20
I can't seem to figure out how to proceed. What am I missing? Do I have to make an assumption of the number of days?
Thanks.
