Answer:
38
Step-by-step explanation:
Let the number of each coin be n.
The total sum of these coins is $4.40. So we can write:
n Nickles + n Dimes + n Quarters = 4.40
0.05n + 0.10n + 0.25n = 4.40
0.40n = 4.40
n = 11
So this means, there are 11 coins of each type.

We will use Partial quotients to find the quotient and remainder of 4024 divided by 68.
Step 1: 
Now, we will subtract 3400 from 4024,
we get remainder as 624.
Step 2: 
Subtracting 340 from 624,
we get remainder as 284.
Step 3: 
Subtracting 272 from 284,
we get remainder as 12.
So, Quotient =
and Remainder is 12.
