Contribution to total grade from midterm grade = 2/3*48 = 32

let Wendy's final grade = x

To score 70 in total:

32 + x/3 = 70

x/3 = 38

Now continue.....

… she got an answer of 65.3 …

This is obviously wrong because the exercise calls for a range of numbers.

Do you know the difference between a range of numbers versus a single number?
