How to pass???

Question

my final math mark was 56%, and I have an exam next week that's worth %20. So what percentage do i have to get on the exam to pass (%50)???

Answer 1

IN ALL MY OTHER SUBJECTS I LIKE TO REVIEW EVERYTHING 3-5 TIMES I ALSO DO THAT IN MATH HOWEVER IT HELPS TO MAKE UP PROBLEMS OF YOUR OWN AND ANSWER THEM BUT IT IS ALWAYS BETTER TO HAVE A "STUDY BUDDY" BUT REVIEW THE TEST STUDY TOOLS BOOKS AND YOUR OWN PROBLEMS IN THE MORNING REMEMBER GET IN BED EARLY AND EAT HEALTHY TONIGHT AND TOMORROW

Answer 2

You need 26%. Not too difficult, but good luck anyways!

How I figured it out:

0.8*0.56 + 0.2*x = 0.5

0.2*x = 0.052

x = 0.26

(0.26)*100% = 26%
