The grading policy for Professor Higgin’s College Algebra class is: midterm (16%), three homeworks (18% each), and final exam (30%). Marcos’ grades are 86 on his midterm test, and 83, 77, and 82 on three homeworks. ***Use this information to answer all questions in this section.***
Solve the equation to find what minimum grade Marcos needs on the final exam in order to earn a B for his course. [HINT: 80 is the minimum grade for a B]. (Round to the nearest whole number). *

step-by-step explanation:

rectangles are made up of 4 right angles, which means that a side and a base meet perpendicular to one another.   their slopes then have to reflect perpendicular slopes.   perpendicular slopes are opposite reciprocals of one another.   for example, if the slope of one line is +2/3, then the perpendicular slope to that would be -3/2.   so we look for that combination in our choices.

all of them satisfy that condition (so what's the question, i guess? )
