Answer:
3 hours
Step-by-step explanation:
24/7 = 3.42 hours and rounded that will be 3 hours
To solve this you need to make all of the percentages for the scores go back 2 decimals. For example: 82 --> 0.82
Next you multiply the decimal by the percent on the test.
0.90 × 75 = 67.5
0.95 × 10 = 9.5
0.82 × 15 = 12.3
Finally you add all of them up and get an answer.
67.5 + 9.5 + 12.3 = 89.3
