Answer:

A(x) = 20000(0.88)^x

Step-by-step explanation:

The general form of these exponential equations is ...

A(x) = a·b^x

where 'a' is the initial value, and b is the annual growth factor. x is the elapsed time in years.

The growth factor is ...

growth factor = 1 + growth rate

Here, the growth rate per year is -12%, so the growth factor is ...

b = 1 -12% = 88% = 0.88

Of course, the initial value is a=20,000, so the equation is ...

A(x) = 20000(0.88)^x

Mrs. Mitchell decided to grade her projects by giving each student 50 points if they turned in a project and then an additional

Let $c$ be the amount of parts the student answered correctly. Suppose that $s(c)$ is a function between $c$ and the score of a student's project. As the student initially receives a fixed $50$ points for turning the project in and $5$ points for each correct part, the function is initially:

$s(c) = 5c+50$

When the students receive $7$ points for each correct part, the coefficient of $c$ changes, as the amount of points received per correct answer increases. Thus:

$s(c) = 7c+50$ .
