Question

Nina graduated from college with 138 credits after passing 40 courses. If each of the courses she passed was worth 3 credits or 4 credits, which of these statements is correct?
-22 of the courses Nina passed were worth 3 credits each.
-Nina earned a total of 54 credits from 4–credit courses.
-22 of the courses Nina passed were worth 4 credits each.
-Nina earned a total of 54 credits from 3–credit courses.

Answer 1

The correct one is: 22 of the courses Nina passed were worth 3 credits each.

Because 22 multiplied by three is 66. 40-22 is eighteen. Then you would multiply 18 and 4 together to get 72. 72+66 is 138.
