Last year at a certain high school, there were 110 boys on the honor roll and 75 girls on the honor roll. This year, the number of boys on the honor roll decreased by 20% and the number of girls on the honor roll decreased by 4%. By what percentage did the total number of students on the honor roll decrease? Round your answer to the nearest tenth (if necessary). PLEASE ANSWER THIS

the solution is the point

step-by-step explanation:

we have

> equation a

> equation b

adds equation a and equation b

substitute the value of x in equation b to find the value of y

the solution is the point

this is a direct variation proportion. y = kx

y is the total amount due, k is the constant of variation, and x is the number of texts sent.

plug in the 3.20 and the 16 to solve for the "k". this is the constant of proportionality. it is the value that will not change.

3.20 = k(16). solving you get $.20 per text.

the equation would then be y = .20x
