Angela has 23 coins in quarters and dimes in her pocket. The total value is $5.00. How many of each coin does she have?
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Let "d" be the number of dimes.
Then the number of quarters is (23-d).
The "value" equation is
10d + 25*(23-d) = 500 cents.
10d + 575 - 25d = 500,
10d - 25d = 500 - 575,
-15d = -75,
d = = 5.
Answer. 5 dimes ans 23-5 = 18 quarters.
