Answer:
His overall grade is 87
Step-by-step explanation:
This grade is a weighed average.
The student got 88 on the homework. The homework is 50% of the grade.
The student got 80 on the midterm exam, that is 20% of the grade.
The student got 90 on the final exam, that is 30% of the grade.
His overall grade is:
G = 0.5*88 + 0.2*80 + 0.3*90 = 87
His overall grade is 87
Answer:
10,000
Step-by-step explanation:
Hello!
"Decrease" means to take away, so subtraction would be used here.
We must find out 15% of 240 is, and to do that we will convert the percentage to a decimal by dividing by 100, and then multiply the decimal by 240.
^ I know, that's probably a lot to take in at once! :D
15% ÷ 100 = 0.15
240 × 0.15 = 36
Now that we know what 15% is, we must subtract it:
240 - 36 = 204
Final Answer:
204 is the total amount after a 15% decrease.
