Question 1053312: A purse contains $3.25 in quarters, dimes, and nickels. The purse contains twice as many dimes as nickels. The purse contains a total of 23 coins. Find the number of each kind of coin. Answer by jorel555(1290) (Show Source):
You can put this solution on YOUR website! Let n be nickels, d be dimes, and q be quarters. Then:
n+d+q=23
We also know that d=2n. So:
n+2n+q=23 and
5n+10(2n)+25q=325
3n+q=23
25n+25q=325
75n+25q=575
50n=250
n=5
d=10
q=8
The purse contains 5 nickels, 10 dimes, and 8 quarters. ☺☺☺☺
