Kevin and Randy Muise have a jar containing 53 coins, all of which are either quarters or nickels. The total value of the coins
lilavasa [31]
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.

Rylee shopped at a clothing store, where she spent $36.50 plus 8% tax. Then, she spent $25 to refuel her car at the gas station.
inn [45]

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
