Question

so someone help me figure this out haha, i have a 93 in my math class,
the final exam is 30% of our grade
whats the lowest grade that i can get on the final and still pass with an A (90)?

Answer 1

93% before the exam?

Answer 2

yes

Answer 3

final exam is next week =(

Answer 4

\[93\times\frac{70}{100}+x\times\frac{30}{100}=90\]

Answer 5

93 * 0.7 = 65.1

x * 0.3 = 0.3x

0.3x + 65.1 = 90

0.3x = 24.9

x = 83

You need at least 83 percent
