Let's start by figuring out how many quarters Irving has. We know that he has $5.25 in total, and since each quarter is worth $0.25, we can set up an equation:
$0.25 * q = $5.25
Dividing both sides by $0.25, we find that Irving has q = 21 quarters.
Next, we know that Irving has 10% as many quarters as nickels. Since we know how many quarters he has, we can set up another equation:
q = 0.1 * n
Substitute the value of q (21) into the equation:
21 = 0.1 * n
Divide both sides by 0.1 to find the number of nickels:
n = 21 / 0.1 = 210
Irving has 210 nickels.
irving, the wishing well diver, has 10% as many quarters as nickels. If irving has $5.25 in quarters and nickels, how many nickels does he have?

No the answer is not 210. The value of the quarters (in dollars) plus the value of the nickels (in dollars) has to equal 5.25
Let's denote the number of nickels Irving has as 'n'. Since he has 10% as many quarters as nickels, he has 0.10n quarters.
The value of the nickels in dollars is 0.05n and the value of the quarters in dollars is 0.25(0.10n) = 0.025n.
We are told that the total value of the quarters and the nickels is $5.25. Using this information, we can set up the equation:
0.05n + 0.025n = 5.25
0.075n = 5.25
n = 5.25 / 0.075
n = 70
Irving has 70 nickels.
The value of the nickels in dollars is 0.05n and the value of the quarters in dollars is 0.25(0.10n) = 0.025n.
We are told that the total value of the quarters and the nickels is $5.25. Using this information, we can set up the equation:
0.05n + 0.025n = 5.25
0.075n = 5.25
n = 5.25 / 0.075
n = 70
Irving has 70 nickels.
