Step 1a. For a card number with an even number of digits (e.g., Visa or MasterCard), double alternating digits starting with the first digit in the sequence.
Step 1b. For a card with an odd number of digits (e.g., American Express), double alternating digits starting with the second digit in the sequence.
Step 2. If the doubling resulted in a number with two digits, add them together to get a single digit number
Step 3. Now go back to the original credit number and replace the digits that you doubled with the new value — either the doubled value, or the doubled value with the digits added together — and add it all up.
Step 4. Check to see if the sum is evenly divisible by 10 (you can simply look to see whether or not it ends with a zero).
If the card number does not pass this check, then it is not a valid number. If, on the other hand, it does pass, then it may be a valid number with valid credit report.
Paul surely charges 75 dollars, and then he adds 40 dollars per hours. This means that the expression for the money he asks is
where 
is the amount of money and 
is the number of hours.
Since 
can be at most 8, this is the case that generates the highest money, so if we plug 
we have
2
explanation:
h(x)= -x-4
h(-6) = -(-6)-4
h(-6) = 6-4
h(-6) = 2
