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 jessica's weighted average in the class rounded to the nearest whole number

To solve the problem, get the percentage of each test by multiplying the score and the percentage then add it all up:

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
