Susan has 50% more books than michael. michael has 40 books. if michael buys 8 more books, will susan have more or less books than michael? what percent more or less will susans books be? use any method to solve the problem

Susan has more books than Michael.

Susan has 25% more books than Michael.

Step-by-step explanation:

Number of books Michael has = 40.

Number of books Susan has = 40+50%(40)=40+20=60.

When Michael buys 8 more books number of books Michael has = 40+8=48.

Michael has less number of books than Susan.

Michael has 60-48=12 more books than Susan.

Percent of books Susan has less than Michael = %.

addition

step-by-step explanation:

the equation of the parallel line would be y = 2x + 9

step-by-step explanation:

to start we need to find the slope of the original line. we can do that by looking at the coefficient of x, which is 2

since the slope of the original line is 2 and parallel lines have the same slope, we know the new line will also have 2 slope. now we can use that along with the point given in point-slope form to get the find equation.

y - y1 = m(x - x1)

y - 5 = 2(x + 2)

y - 5 = 2x + 4

y = 2x + 9
