Formulas make everything easier
The first semester accounts for 30% of my final grade, the second semester accounts for 40% of my final grade, and my final test accounts for the rest.
If I got a 98 for my first semester, a 92 for my second semester, and want to get a 95 as my final grade, what must be the minimum score on my final? (94.5 rounds up to 95)
(round to the tenths place)
