Your final grade in math class is calculated by adding 75% of your semester average to 25% of your final exam grade. If your semester average is 88, what grade must you get on the final exam in order to get an A- for your final grade? (Note: An A- is for a final grade of 90-92) Please show work.

Respuesta :

If u get a 96 on the exam u would get a 89.6% average which would round up but if u don’t do rounding then u would have to get a 98 to get exactly a 90% average.
