An algebra test had two parts. Part I had 40 problems, and part II had 60 problems. Bernard got 80% of the problems on part I correct and 90% of the problems on part II correct. What was the total number of problems that Bernard got correct on the test?

How do I figure this out?

An algebra test had two parts.

=> Part I had 40 problems

=> and part II had 60 problems.

Bernard got 80% of the problems on part I correct and 90% of the problems on part II correct. What was the total number of problems that Bernard got correct on the test.

Part 1

=> 40 problems and Bernard was able to answer correctly that 80% of it

=> 40 *.80 = 32 questions are correct

Part 2

=> 60 problems and Bernard was able to answer correctly the 90% of it.

=> 60 *.90 = 54 questions got correct answers.
