Upper level algebra How many points do you need on the final to average 75? 2021-01-08
Your grades in the three tests in College Algebra are 87, 59 and 73.
Calculation:
Let x = the final test grade
Average of four grades = 75
Therefore, $$\frac{87+59+73+x}{4}=75$$
$$\frac{219+x}{4}=75$$
$$219 +x = 300$$
$$x=81$$
Hence, the final test grade is 81.
