Each test score (62, 83, 91) are worth 20% so they have the weight 0.2.

Term project score  (88) is worth 25% so it has weight 0.25

Homework score (76) is worth 15% so it has got weight 0.15

So here (weighted) mean score = weight*score = 0.2*62+0.2*83+0.2*91+0.25*88+0.15*76 = 80.6

Mean score is 80.6
