Question 1042100
A collection of dimes and quarters has a total value of $2.20. If there are three times as many quarters, how many of each coin is in the equation?
--------------------
10d + 25q = 220 cents
q = 3d
---------------------
Substitute for "q" and solve for "d"::
10d + 25(3d) = 220
10d + 75d = 220
85d = 220
d = is not a positive whole number

Please check you post for accuracy.
