Q:

# Caroline bakes brownies to give to her friends. She starts with 48 brownies and gives a brownie to 6 friends each hour until she has none left.Use the Segment tool to plot a graph representing the number of brownies Caroline has left to give away from the time she begins giving them away until she has no brownies left.

Accepted Solution

A:
Answer: The  below figure shows the graph of the given situation.Step-by-step explanation:Since, at first Caroline has brownies= 48And, according to the question, it is decreasing by 6 per hour.Then, the function of the given situation can be written as,f(x)=48 - 6 x,     ------ (1)where,  x is the number of hours and f(x) is the number of brownies Caroline has left in x hour.Thus by substitution x= 0,1,2,3,4,5,6,7,8 in equation (1),We get, f(x)=48, 42, 36, 30, 24, 18, 12, 6, 0So, the function has points, (0, 48), (1, 42), (2, 36), (3, 30), (4, 24), (5,18 ),(6,12 ) (7, 6) (8, 0).With help of the above points we can draw the graph of the given situation.Note: since at x=8, f(x)=0 therefore after 8 hours she has no brownies left.
