That is a very good score! Don’t be disappointed. It’s okay to retake the SAT if you are not happy with the score. Most colleges take your highest score anyways. Good job!
Answer:
$3,100.
Explanation:
Given that tuition for one year at Mount Tusk University is $ 13,400, and Elijah has saved $ 1,800 for this year's tuition, while his parents have agreed to pay $ 5,000 this year, and he earned a football scholarship for $ 3,500, given that Elijah hopes to earn the rest of the money through his work-study job tutoring in the math center, to determine how much money does Elijah need to earn tutoring, the following calculation must be performed:
13,400 - 1,800 - 5,000 - 3,500 = X
11,600 - 5,000 - 3,500 = X
6,600 - 3,500 = X
3,100 = X
Thus, Elijah needs to earn $ 3,100 in his work-study job.
