Since f(2) is not given in the function definition, you must use f(n) with n=2. That tells you
... f(2) = -29 -f(1)
Now, f(1) is defined, so use that value.
... f(2) = -29 -(-16) = -29 +16
... f(2) = -13
(new - original)/original = mark up
(78.08-64)/64= mark up
14.08/64 =mark up
.22 = mark up
multiply by 100 to get to a percent
mark up = 22 percent
2n+8=-48
2n=40
divide by sides by 2
n=20<span />
Answer:
Second option is the correct choice.
Step-by-step explanation:
We need to focus on the given details to fit the data into the formula of slope. To find the slope we need two points. The second point is already given which is
To identify the first point, focus on the word "base". It means rate at 0 minutes. So the second point will be
Inserting the values, we get:
