Hi! I think I got the answer, it is a tricky one! The answer I got was C) 1029.

Step-by-step explanation:

1. It is good to first know that 40%more means 1.4 (some number). So, if n is 40% more than the sum of the other three numbers: n= 1.4* (l +m+p) .

2. Also note that: n+l+m+p= 1764; so, n = 1764-l-m-p.

3. Since we have two expressions for n, we can equate them to each other. Giving, 1.4* (l +m+p) =1764-l-m-p . Simplifying we get 2.4 (l +m+p)=1764.

4. l +m+p =1764/2=735.

5. 1764-735=1029

Hope that helps! Feel free to message back if there are any questions!

Answer:

D. Both functions are decreasing at the same average rate on that interval

Step-by-step explanation:

The dashed lines on the attached graph of the two functions (f in red, g in purple) represent the average rate of change of each function on the interval. The lines are parallel, because the average rate of change is the same for each of the functions on that interval.

Function f decreases by 60 units from f(0) = 64 to f(4) = 4 on the interval x = [0, 4]. Function g decreases by 60 units from g(0) = 75 to g(4) = 15 on the same interval. The average rate of change is the amount of decrease divided by the interval width. Those values are the same for both functions.
