Question 925794
A purse contains $1.35 in nickels and dimes. In all there are 19 coins. How many of each coin are there?
-----------------
Coin Equation: n + d = 19 coins
Value Equation:5n + 10d = 135 cents
---------------------------
Modify for elimination::
5n + 5d = 95
5n + 10d = 135
------
Subtract and solve for "d"::
5d = 40
d = 8 (# of dimes)
----
Solve for "n"::
n = 19-8 = 11 (# of nickels)
