Solve using system of equations. y=number of constructed response questions x=number of multiple choice questions x+y=27 y=10x-6 Replace y for 10x-6 in the first equation x+(10x-6)=27 Simplify. 11x=33 x=3 Substitute 3 for x in any equation to get y=24 there are 3 multiple choice and 24 constructed response questions.
120 + 90 = 210 points 350 - 210 = 140 OR 351 - 210 = 141 (if it must be more than 350, you need <em>at least </em>351 points total, or 141 more points, to get a grade B)
