Mary has 11 more nickels ($0.05) than quarters ($0.25). How many coins doesshe have if the total value of her coins is $2.65?

17 18 19 20 21

Please help me find the flaw in my reasoning. Thanks

q=quarter

n=nickels

n=q+11

0.05n+0.25q=2.65

0.05(q+11) +0.25q=2.65

0.3q=2.1

--> q=7, so n=7+11=18

the coins she has are =n+q=7+18=25. There is no 25 in the list of answer choice

I believe there is nothing wrong your logic.

Question seems to be wrong..

"Question should ask how many nickels does shes has.." and answer would be 18
