Question 249063
If I have a 75.5% in a class, and the final is worth 20% of my grade, what do I need to get in order to pass the class with a 73%;
:
If the final is 20%, then the 75.5% is 80% of your grade then
:
Let x = final grade
:
Do it this way
{{{(2x + 8(75.5))/10}}} = 73
:
{{{(2x + 604)/10}}} = 73
Multiply both sides by 10
2x + 604 = 730
2x = 730 - 604
2x = 126
x = {{{126/2}}}
x = 63% will get a 73%
;
:
Check this
{{{(2(63) + 604)/10}}} = 73
