Michelle used a $20 bill to pay for a notebook that only cost p dollars. How much change did Michelle receive from the cashier?

Write your answer as an expression.

The real answer is 20-p

yes

the heck

well if it cost 5 dollars you would get:

Change = 20 - 5

20-5

suck to be u failing

Suppose I say

Michelle used a $20 bill to pay for a notebook that only cost $12. How much change did Michelle receive from the cashier?

If you can solve that, just write down the steps you took, only use p instead of 12.
