On a violin achievement test, the final score is made up of 75% performance, 10% sight reading, and 15% written theory. Samantha earned an average score of 90 on performance, 95 on sight reading, and 82 on written theory. What was Samantha's final score for the violin achievement test? Please help asap!

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
Samantha achieved a 89.3% on her test.
