A cashier has a total of 105 bills, made up of tens and hundreds. The total value of the money is $6450. How much of each kind does he have?
-----------
Quantity Eq: t + h = 105
Value Eq: 10t+100h = 6450
----------------------------------
Modify the equations:
t + h = 105
t + 10h = 645
-------------------
Subtract the 1st from the 2nd and solve for "h":
9h = 540
h = 60 (# of hundred dollar bills)
t = 105-60 = 45 (# of ten dollar bills)
