71 x 0.85 = 60.35
60 x 0.15 = 9.00
Your grade is 60.35 + 9.00 = 69.35.
85% of your grade is a 68 and 15% is zero. 0.85 x 68 + 0.15 x 0 = 58, your final grade.
7.5 is 15% of 50.
To calculate a 15 percent decrease, first determine the original amount. Then, multiply that amount by 0.15 to find the decrease in value. Subtract this decrease from the original amount to get the final value. For example, if the original amount is $100, the decrease would be $15, resulting in a final value of $85.
You have what's known as a weighted average. The 80 score is weighted more heavily than the 91 score, so the weighted average will be closer to 80 than a non-weighted average. 0.85 x 80 = 68 0.15 x 91 = 13.65 68 + 13.65 = 81.65
The final price of the item, including the discount and sales tax, is: $73.44
71.4 84*.85+0*.15=71.4
85% of your grade is a 68 and 15% is zero. 0.85 x 68 + 0.15 x 0 = 58, your final grade.
You do not even need to get a 30% on the final. If you have a 100% in the class and get a 0% on the final, you willl still have an 85% in the class.
15 out of 20 would be grade of 75 percent.

Take your number and multiply by .85
.5985 (final total after discount: 3.3915)
Exactly 53.33333333% (53.33) percent. As a grade, it is an F
To find the result when 320 is decreased by 15 percent, you first calculate 15 percent of 320 by multiplying 320 by 0.15, which equals 48. Then, subtract 48 from 320 to find the final result. The result of decreasing 320 by 15 percent is 272.
