Question 176297: A coin bank contains $2.05 in nickels and dimes. There are 5 more nickels than dimes. What equation correctly represents this information?
1.5(d + 5) + 10d = 205
2.5n + 10(n - 5) = 205
3.5n + 10(n + 5) = 205

You can put this solution on YOUR website!
If you call the number of dimes d, then the number of nickels is d+5. The dollar amount of dimes would be 0.10d and the dollar amount of nickels would be 0.05(d+5). So the coin back having 2.05 means
0.10d%2B0.05%28d%2B5%29=2.05
If you multiply both sides of the equation by 100, you get
10d%2B5%28d%2B5%29=205 which is the first option.
