Question

6. Jessica wants to calculate her grade in her accounting class. She has four test grades (82, 65, 71, and 77) and a homework grade (92). Her highest test grade counts for 25% of her grade, her lowest test grade counts for 15% of her grade, the two remaining tests count for 20% each and her homework grade counts for 20%. What is Jessic weighted average in the class rounded to the nearest whole number?

Answer 1

We need to calculate the percentage of each test by multiplying the score and the percentage then add it all up

i.e,

82 * .25 (highest test grade) + 65* .15 (lowest test grade) + 71*.20 (each test remaining) + 77*.20 (each test remaining) + 92*.20 (homework grade)

= 20.5 + 9.75 + 14.2 + 15.4 + 18.4

= 78.25 or 78% in whole number
