So here is how you'll get the answer.
Let x be the number of quarters in the jar. 
Then 53-x is the number of nickels in the jar. 
<span>We also know .25x + 0.05 (53-x) = 10.25
</span>So next, we solve for x.
.25x + 2.65 - 0.05x = 10.25
0.2x +2.65 = 10.25
0.2x = 10.25 -2.65
0.2x = 7.40
x =37
Therefore, there are 37 quarters in the jar.
53-37 is 16. So there are 16 nickels in the jar.
Hope this answer helps.
