What number could Mr. Alberto use to determine the student's grade if he used his grading scheme? b. Write an algebraic expression to generalize the scoring procedure for Mr. Alberto's class to allow him to use any percentages he likes for the scoring scheme. Clearly describe what the variables represent. a. The student's final grade was using the grading scheme. (Type an integer or a decimal.) b. The expression should be x% (TP) + y% (HW) + where x is the percent the term paper is worth, y is the percent of the grade the homework is worth, and TP, HW, and FE are the grades for the term paper, homework, and final exam, respectively. ter or answer in the answer box
