Question

If I have an 85% in my class and my final is worth 20% of my final grade, what do I need to get on my final to get at least an 80% in the class?

Answer 1

solve
\[.8\times 85 + .2\times x \geq 80\] for x

Answer 2

i.e. 80 percent of your grade is 85, twenty percent is the final (which you don't know yet) and you want that larger than 80
can you solve this?
