Answer :
Answer:
To represent Sarah's SAT score after attending any given number of classes, we can define the following variables:
S = Sarah's SAT score
C = Number of classes attended
According to the test prep company's claim, each class attended increases Sarah's score by 10 points.
To write an expression representing Sarah's SAT score after attending any given number of classes, we can use the formula:
S = 850 + (10 * C)
In this expression, 850 represents Sarah's initial SAT score, and 10 * C represents the increase in score for each class attended.
For example:
- If Sarah attends 3 classes, the expression would be:
S = 850 + (10 * 3)
S = 850 + 30
S = 880
Therefore, after attending 3 classes, Sarah's SAT score would be 880.

Final answer:
The key variables are Sarah's initial SAT score of 850 and the number of classes she attends. The expression to calculate her score after attending any number of classes is S + 10n, where S is her initial score and n is the number of classes.
Explanation:
In this case, Sarah's initial SAT score and the point increase per class are the key variables. If we denote Sarah's initial SAT score as S, which is 850, and the number of classes she attends as n, the expected increase in her score for each class is 10 points.
So, the expression to calculate Sarah's SAT score after she attends any number of classes will be: S + 10n. This means that each time Sarah attends a class, we add 10 points to her initial score of 850.
