10 nickles and 6 dimes.

?

Lets let x=number of nickels. Since there are 16 total coins, (16-x)=number of dimes. We know the value of the coins is 1.10. So, 10 times the number of dimes plus 5 times the number of nickels equals 110 cents. Or:
\[5x+10(16-x)=110\] or-
\[5x+160-10x=110\] combine like terms and simplify and you find
\[x=10 nickels\]

You just changed the question.
OpenStudy (anonymous):
oh boo! It isnt possible! you would need a penny!
OpenStudy (anonymous):
With the value now 1.11, you'd find
\[x=10.2 nickels\] which wouldn't be possible. The question is unsolvable.

No I didnt, the question wasnt changed. And @britanny_ is getting somewhere.

Wanna know the answer? It's dumb. My friend told me.
