<span>Let x=number of nickels in the piggy bank
(2x+3)=number of dimes in the piggy bank
(3x-3)=number of quarters in the piggy bank
.05x+.10(2x+3)+.25(3x-3)=14.55
.05x+.20x+.30+.75x-.75=14.55
</span>
<span>
1.00x=14.55+.45
x=15
2x+3=33
3x-3=42
The number of nickles in the piggy bank would be 15.

<span><span>The number of dimes in the piggy bank would be 33

<span>The number of quarters in the piggy bank would be 42. </span>
