Let "x" be the number of classes Sarah must take in order to earn the average score of 1060. Since her score will increase by 10 points for each class she attends, her final SAT score will be 1060 + 10x.
The equation to determine the number of classes Sarah must take is:
1060 + 10x = 1060
Simplifying the equation, we have:
10x = 0
Dividing both sides by 10:
x = 0
Thus, Sarah must take 0 classes in order to earn the average score of 1060.
Part B: The average SAT score for the college is 1060. Suppose the company's claim is correct and her score will increase by 10 points for each class that she attends. Write and solve an equation to determine the number of classes Sarah must take in order to earn the average score.(3 points)
