A student in a Pre-Calculus class has test scores of 76, 60, 79, and 73. The final exam is worth 2 test grades.

Question

Write a linear equation that models this problem, where x is the grade on the final exam and y is the student's grade in the course.

Answer 1

y = weighted average of sum of grades

y = (76+60+79+73+2x)/(4+2) = 288/6+ 2x/6 = 48+x/3 = final grade with x= final exam score

You got it correct
