The inequality that represents the number of right answers (r) and wrong answers (w) Olga can give to win the contest is: 
<u><em>Explanation</em></u>
Number of right answers is
and number of wrong answers is 
Olga earns 12 points for each right answer and loses 4 points for each wrong answer.
So, total points earned for
right answers
and total points lost for
wrong answers 
That means, <u>her score will be</u>:
points.
In order to win the quiz contest, Olga must score <u>more than 400 points</u>. So, the inequality will be.......

It would be 40% is an apple at first, the peach would be 66%.
Firs month A
Second month 3A
Third month 3*3A = A (3^2)
Fourth month A(3^3)
Fith month A (3^4)
nth month A (3 ^ (n-1) )
That is an exponential model, because the variable (time, n) is the exponent of the formula.
