Matt scored 75 on the calculus midterm. If the final exam counts twice as much as the midterm exam, then for wht range of scores on the final would Matt get an average between 81 and 92?

  • College Algebra -

    average=(75+2*FE)/3
    solve for FE given average is 81, then 92

    another way to look at it: if he wants an 81, and is already 6 point behind that, then he needs 3 points on the FE above 81 to score that average.

    scored 56, needs between 76 and 87
