Nicholas used a 10 dollar bill to pay for a granola bar that only costs p dollars.

$10 - $p

10-P

To find out how much change Nicholas would receive, you need to calculate the difference between the cost of the granola bar and the 10-dollar bill.

The change can be calculated using the equation:

Change = 10 - p

Please provide the value of p, and I'll be able to calculate the change for you.

To find the amount of change Nicholas will receive, we need to subtract the cost of the granola bar from the amount that he paid.

The equation for this would be: Change = Amount Paid - Cost of Granola Bar

In this case, Nicholas paid with a 10 dollar bill, so the amount paid is $10. The cost of the granola bar is p dollars.

So, the equation becomes: Change = 10 - p.

Therefore, the amount of change Nicholas will receive is 10 - p dollars.
