You can put this solution on YOUR website! The box currently contains 44 coins, consisting of pennies, dimes, and quarters.
Quantity equation: p + d + q = 44
---------------------------------------------
The number of pennies is equal to the number of dimes,
Quantity equation: p - d = 0
------------------------
the total value is $4.37.
Value equation: p + 10d + 25q = 437 cents
---------------------------------------
How many of each denomination of coin does he have in the box?
--------
You have three equation with three variables:
p + d + q = 44
p - d + 0 = 0
p + 10d + 25q = 437
------------------------
Use any method you know to solve this system to get:
p = 17
d = 17
q = 10
