You can put this solution on YOUR website! A collection of loonies, toonies, and quarters has a value of $25.50. There is one more looney than there are toonies, and there are twice as many quarters as toonies. How many of each kind of coin are in the collection?
------------------------------
Quantity Equation: L = T + 1
Quantity Equation: Q = 2T
Value Equation: 100L + 200T + 25Q = 2550 cents
----------------------------------------------
Substitute to solve for "T":
100(T+1) + 200T + 25(2T) = 2550
100T + 100 + 200T + 50T = 2550
350T = 2450
T = 7 (# of toonies)
Since L = T+1, L = 8 (# of loonies)
Since Q = 2L, A = 16 (# of quarters)
