Answer 1

Answer:

let 'x' be the number of $10 notes, and

'y' be the number of $50 notes,

x+y=22 -----(1)

10x+50y=500 -----(2)

by solving (1) and (2)

10x+10y = 220

10x+50y = 500

-----------------------

40y = 280

y= 7 -----(3)

substitute (3) in (1)

x+7= 22

x=15

Therefore, $10 notes are 15

and $50 notes are 7
