PLEASE ANSWER ASAP: Danielle's wallet had $2.65 in change:all quarters,dimes and nickels. She had 3 times as many quarters as di
Butoxors [25]
We can write an equation in terms of n, the amount of nickels:

25(3n+3)+10(n+1)+5n=265.

Thus:

90n+85=265

Subtracting 85, we have:

90n=180

Therefore, n=2.  As such, Danielle has 2 nickels, 3 dimes, and 9 quarters.
