I suppose that you should have given some pairs to choose from.
Anyway, I can tell you how to do it. Given a pair 
, you have to substitute 
and 
to 
and 
respectively, and see if you get something true.
For example, the pair 
satisfies the function, because the substitution yields
which is true. On the other hand, the pair 
doesn't satisfy the function, because
is clearly false.

Answer:
There are 21 twenties and 8 fifties in the drawer.
Step-by-step explanation:
This question can be solved by a system of equations.
I am going to say that:
x is the number of twenties
y is the number of fifties.
A cash drawer contains 29 bills.
This means that x + y = 29.
The total value of the bills is $820.
This means that 20x + 50y = 820.
So
x + y = 29
20x + 50y = 820
From the first equation, x = 29 - y. So:
20x + 50y = 820
20(29 - y) + 50y = 820
580 - 20y + 50y = 820
30y = 240
y = 8
And
x = 29 - y = 29 - 8 = 21
There are 21 twenties and 8 fifties.
