Question

My math teacher sucks, please help.

Answer 1

Answer:

Concept: Rate of Change

1. We are told that the rate of change is 3x d/dx and we want to find the rate for 12 hours hence we do 12÷ 3 to get 4 hours
2. You are told she babysat for 2 hours, each day for a total of 10 days = 20 hours. She earned 180 dollars so 180/20 hours = $9 per hour
3. So you have a table and it tells you that for every quart you need 4 bags of tea. Hence for 24 bags we will get a result of 6 quarts of tea
4. You are told you have 35 total items between x= bottle and y= bars. You have 7 friends and each carry 3 water bottles = 21 water bottles. Hence 35-21= 14 bars
5. Rate positively and give brainlist
