720 codes.
There are 10 digits possible for the first digit of the code.
Since there can be no repeated digits, you subtract 1 and find there are only 9 possible digits for the second digit in the code.
Finally, subtract 1 again to find there are only 8 possible digits for the last digit.
Multiply these together to find the number of combinations.
10 * 9 * 8
90 * 8
720
So, there are 720 combinations if digits cannot be repeated.

Answer:
$8.44
Step-by-step explanation:
To find the 20%
x/14.45=20/100
14.45×20=289
289÷100=2.89
We then subtract 2.89 from 14.45 to get the selling price.
14.45-2.89=11.56
$11.56 is the price of the baseball hat on sale.
To get the change
20-11.56=8.44
$8.44 is the change
