tira and francisco applied to the same college. they looked up the average SAT score of students admitted to that college. tiras SAT score was 290 points above the average score. Francisco SAT score was 10 points below the average score. which expression represents the difference in their scores?
Let x represent the average SAT score of students admitted to the college.
The expression representing Tira's SAT score would be x + 290.
The expression representing Francisco's SAT score would be x - 10.
To find the difference in their scores, we can subtract Francisco's SAT score from Tira's SAT score:
(x + 290) - (x - 10)
Simplifying this expression, we get:
x + 290 - x + 10
Combining like terms, we get:
300
Therefore, the expression representing the difference in their scores is 300.
