Susan has 50% more books than micheal. Micheal has 40 books. If Michael buys 8 more books will Susan have more or less books than micheal? What percent more or less will Susan's books be?

S usan will have 25% more books than Michael

Step-by-step explanation:

First we have to calculate how many books Susan has

x = Susan's books

50% = 50/100

x = 40 + 40 * 50/100

x = 40 + 20

x = 60

y = Michael's books

y = 40 + 8

y = 48

60 > 48

S usan will have more books than Michael

To know the percentage of more that susan will have we have to divide the quantity of susan's books by michael's

60/48 = 1.25

To find the percentage we multiply it by 100 and subtract 100

1.25 * 100 - 100 =

125 - 100 = 25%
