number of tens --- x
number of fives --- x+4
number of twenties -- 2x-3
now for their value:
10x + 5(x+4) + 20(2x-3) = 290
solve for x, sub back into my definitions
wallet contains $290 in $5, $10, and $20 bills.
The number of $5 bills exceeds the number of $10 bills by 4, and the number of $20 bills is 3 less than twice the number of $10 bills.
