Question 1011883
x = number of p100 bills.
y = number of p50 bills.


100x + 50y = 25000


x = 2y


replace x with 2y in the above equation to get:


100x + 50y = 25000 becomes 200y + 50y = 25000


combine like terms to get 250y = 25000.


solve for y to get y = 25000 / 250 becomes y = 100


since x = 2y, then x = 200.


your solution is number of p100 bills is 200 and number of p50 bills is 100.


200 * 100 = 20000
100 * 50 = 5000
20000 + 5000 = 25000
