Answer 1

2.65=3x(25)+x(10)+(x-1)(5)
9 quarters 3 dimes 2 nickels
9*.25+2.25
3*.10=.30
2*.5=10
2.25+.30+.10=2.65

Answer 2

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.
