Final Answer:
Richard needs to earn a total of 510 points to average 85% on his 6 tests.
Step-by-step explanation:
To find the total points Richard needs, we first calculate the average points he wants per test, which is 85% of 80 points (the maximum score per test). So, 0.85 * 80 = 68 points per test. Since he has 6 tests, we multiply the average points per test by the number of tests: 68 points/test * 6 tests = 408 points. Therefore, Richard needs to earn a total of 408 points to achieve an 85% average on his tests.
This calculation ensures that the average percentage aligns with his goal of 85% for all 6 tests. Achieving this total will secure the desired average across the tests.
Setting realistic academic goals and understanding the corresponding point requirements is crucial for students to plan their study strategies effectively and work towards achieving their desired grades.
