Let

be the amount of parts the student answered correctly. Suppose that

is a function between

and the score of a student's project. As the student initially receives a fixed

points for turning the project in and

points for each correct part, the function is initially:

When the students receive

points for each correct part, the coefficient of

changes, as the amount of points received per correct answer increases. Thus:

.
There are 10 trucks and 18 tractors
I found that out by multiplying 10 and 1.8 which gave me 18
when u add 10 and 18 u get 28
C would equal -3 because you are going up 9 units
4.56/-2/1/2pi/14/2 is the answer
$3299.62
- compounded daily interest :

total money he will have : $13,123.62
- amount earned : $13,123.62 - $9,824 = $3299.62
