Question

Final grades are often computed using weighted averages. Some college professors use complicated weighted averages. Your college professor tells you he will give a 33%-67% split on grades between tests and homework where whichever average is higher will be the 67%.

What will your final grade be if your homework average is 85 and your test average is 76?

Answer 1

Answer:

• ≈ 82

Step-by-step explanation:

Add 67% of 85 to 33% of 76:

• 85*0.67 + 76*0.33 = 82.03 ≈ 82

Answer 2

67% of 85

$\\ \sf\longmapsto \dfrac{67}{100}\times 85$

$\\ \sf\longmapsto 85(0.67)$

$\\ \sf\longmapsto 56.95$

33% of 76

$\\ \sf\longmapsto \dfrac{33}{100}\times 76$

$\\ \sf\longmapsto 76(0.33)$

$\\ \sf\longmapsto 25.08$

Add both

$\\ \sf\longmapsto 56.95+25.08$

$\\ \sf\longmapsto 82.03$
