Question

At the end of the semester, Jeremy has the following grades.

exams 72, 65, 54

My Lab 65%

Homework 30 points

final exam 142

Based on his work in the final exam, Jeremy is able to replace exam 3 with 70 points. Find Jeremy's total number of points, express the total as percent, and determine Jeremy's letter grade.

Answer 1

72, 65, 54 replaced by 70

+ final 142-70 = 74

+ lab=hw = 60% of 30 points = 18

problem is far too unclear to make a credible calculation but here goes

72, 65, 70 74, 18

add them divide by 5

= 299/5 = about 300/5 = 60
