Write your answer as an expression.

Answer 1

`\$(10-p)`

Explanation:

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

To find much change Nicholas received, simply subtract the cost of granola bar from the amount of money Nicholas paid:

`\$(10-p)`

For example, if granola bar costs p=$4, then Nicholas gets

`\$(10-4)=\$6`

as a change.
