Answer:
Number of $5 bills = 92
Number of $50 bills = 23
Explanations:
Let the number of $5 bills be x
Let the number of $50 bills be y
There are four times as many $5 bills as $50 bills
x = 4y
The total amount of money = $1610
5x + 50y = 1610
since x = 4y
5(4y) + 50y = 1610
20y + 50y = 1610
70y = 1610
y = 1610 / 70
y = 23
x = 4y
x = 4(23)
x = 92
There are 92 $5 bills and 23 $50 bills
