Question 1010372: Cody works in movie theatre selling tickets. At the end of the evening he has $524 in two and five dollar bills the total number of bills was 145. How many of each kind of bill does he have? Answer by addingup(3677) (Show Source):
You can put this solution on YOUR website! 2 dollar bills: x
5 dollar bills: y
----------------------------------------------
x+y= 145 Subtract x from both sides:
y= 145-x We'll use this value for y next.
-----------------------------------------------
2x+5y= 524
2x+5(145-x)= 524
2x+725-5x= 524 Now subtract 925 on both sides and add/subtract x on left:
-3x= -201 Divide both sides by -3 (remember, -/- = +)
x= 67 He has 67 two dollar bills and
145-67= 78 He has 78 five dollar bills.
----------------------------------------------------
Check:
67*2= 134
78*5= 390
