Question 480037
There were 204 coins on the table. They are all nickels and quaters. The total value is 30.60. How many coins are quaters and how may nickels?
=====================================================================
Let q = the number of quarters
Then 204 - q = the number of nickels
The total amount is $30.60 = 3060 cents
So we can write the following for the total value:
25q + 5(204-q) = 3060
Solve for q:
25q + 1020 - 5q = 3060
20q = 2040
q = 102
So there are 102 quarters and 102 nickels
