Math Help
I am trying to figure out what grade my child needs to earn on his final exam in order to get a B in his class.
The final is 15 percent of his grade. He currently has a 91. I tried doing the math the way I thought it should be done, but the way I did it, he could get a failing grade on the exam and still get a B. That does not seem right to me. I did (91)(.85) + .15x = grade he wants and solved for x. That seems too simplistic. Help?
