Problema Solution
in class, students can complete extra-credit assignments for either 7 points or 12 points. each student can complete at most four of the 7-points assignment and at most four of the 12-point assignments.
If Barbara completes six extra-credit assignments, what is a possible number of points she can get?
Answer provided by our tutors
She wants to maximize the number of points, so she completes four out of six of the 12-point assignments and then can complete two of the 7-point assignments.
4*12+2*7
62
So 62 is the most points she can get.
