Answer 1

The student's score test is given by:

10s + 5m

s: number of correct short answer

m: number of correct multiple-choice answer

Noor answers 16 multiple-choice items correctly, then, m = 16, and she does not answer any short item, that is, s=0.

The total score is obtined by replacing s = 0 and m = 16 in the expression 10s + 5m, just as follow:

10(0) + 5(16) = 0+ 80 = 80

Hence, Noor's score is 80 points
