Question 967016
{{{"80%"=80/100=0.8}}} and {{{"20%"=20/100=0.2}}}
If the grade for the final is {{{x}}} ,
that would give you an average grade of
{{{0.8*101+0.2x=80.8+0.2x}}}
For an an average grade of {{{94}}} you need {{{x}}} to be the solution to
{{{80.8+0.2x=94}}}
Solving:
{{{80.8+0.2x=94}}}
{{{0.2x=94-80.8}}}
{{{0.2x=13.2}}}
{{{x=13.2/0.2}}}
{{{x=66}}}
Of course, you may be able to count on rounding,
so you may have to solve
{{{80.8+0.2x=93.5}}} , whose solution is {{{63.5}}} ,
meaning that a 64 on the final would still give you an A.
