Last year at a certain high school, there were 125 boys on the honor roll and 80 girls on the honor roll. This year, the number
of boys on the honor roll decreased by 8% and the number of girls on the honor roll decreased by 5%. By what percentage did the total number of students on the honor roll decrease? Round your answer to the nearest tenth (if necessary).
Not sure about the first one but the second one is option c (or -3). You just have to factor and find the solutions (so it would be -7 and 4 and then u just add them)
