Me im stick on this algebra 2 question

Hi I’m Charles from the University of Alaska Mathematics Department. I have a degree in dentistry, chemistry, zoology, algebra, geometry and finally literature. Anyways I was very interested by your question so I took a look and saw that this indeed is a hard question. However when I look at it it doesnt look to bad but it could pose to be quite difficult. So assuming from the question I could tell that you need to define the square root untill you hit the zero degree of -2. But you could instead solve for negative externalities of the equations and then use the Calvin formula to solve this question. So ultimately the answer is A. I hope this helps!

Answer for 2: his profit would be $2.88 explanation: you have to first multiply 72 and 0.12 together to get $8.64 once you do that you know how much money the shopkeeper made from selling the candy bars individually. so you have to do 8.64-5.76=2.88 hope that ; )answer for 3: yeah i’m sorry i have no idea what number 3 is. i’m sorry i couldn’t with that.
