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.

Answer: The net change to her banking account balance is $83.22.
Step-by-step explanation:
Hi to answer this question we have to analyze the information given:
She spent $36.50 plus 8% tax. ( to calculate the tax amount we have to multiply the cost by the percentage in decimal form)
36.50 x (8/100) =$2.92 (value of tax)
Adding to the original cost
36.50+2.92 = $39.42
Then, she spent $25 to refuel her car at the gas station.
39.42 +25 = $64.42
She bought groceries worth $23.50. At the grocery checkout, she handed over a coupon for a 20% discount on her purchase
23.50 x (20/100) = 4.7 (amount of discount)
Subtracting to the purchase
23.50 -4.7= $18.8
Finally, adding to the total cost.
64.42 +18.8 = $83.22
