You can put this solution on YOUR website!
Let that same amount of coins of each kind be x.
Then
.01x + .02x + .05x + .10x + .20x + .50x + 1.00x = 282.00
1.88x = 282.00
x = 
x = 150
Yes, it is possible to have 150 each of the 7 coins.
That will be 150×7 or 1050 coins.

How many coins all together, will he get
:
Let's see if it is possible; let n = number of each coin
:
.01n + .02n +.05n + .10n + .20n + .50n + 1n = 282
Add all them n's and we have
1.88n = 282
n = 
n = 150 coins of each value
:
Their are seven kinds of coins: 7 * 150 = 1050 coins in all

Not that hard, right?
