What is a mixture word problem?
The mixture word method or mixture word problem is a method in mathematics to solve the problem when creating a mixture of two or more different things. This method will solve the problem of determining the quantity of mixture result.
In the question, we will mix two grades. So,
= (current grade * current worth grade) + (final exam grade * final exam worth grade)
= (85% * (100%-10%)) + (85% * 10%)
= 76.5% + 8.5%
= 85%
Thus, your final grade doesn't change if you get 85% on a final exam.
