The cash register drawer has 267$ in bills. none of the bills are greater then 10$. the drawer has 11 10$ bills and seven fewer $5 dollar bills then 1$ bills. how many $5 and 1$ bills are there

Part A) -12/2

Part B) The expression would be -6. My answer means that the temperature dropped by 6 degrees Celsius every week and .85 degrees Celsius per day.

Step-by-step explanation:

To do Part A, you need to divide -12 by two to figure out how much it dropped each week. We divide by two because there are two weeks. The way we get how much it drops each day is we divide how much it dropped a week by 7 since there are 7 days in a week. :)
