TEAS Math Problem Solving Practice Test 1

Question : 9 of 40

Marks: +1, -0

Loral received all her grades for the semester (in parentheses) along with the weight for each grade, shown below.
Weight

45 \%=3

tests

(80 \%, 75 \%, 92 \%) 25 \%=

final

(88 \%) 15 \%=

paper

(91 \%) 15 \%=2

oral quizzes each worth 25 points

(22,19)

What is her final grade?

Solution:

Calculate the weighted average of the 3 tests:

((80+75+92)) \/ 3=82.3 \;\text "; "\;

Calculate the average of the 2 oral quizzes:

(22 \/ 25) × 100=88 \;\text " and "\;(19 \/ 25) × 100=76 \;\text ", so "\;(88+76) \/ 2=82 \;\text ". "\;

Multiply each grade by their weight, and then add them all up to determine the final grade: (82

× 0.45)+(88 × 0.25)+(91 × 0.15)+(82 × 0.15)=85
