Explanation:

Percentages

last month the spider ate 8 bugs

it then ate 25% more bugs this month , meaning :

100% was last month ,

this month its 100% + 25% . (this is because it increased by 25% more)

we can make use of cross multiplication :

bugs : percentage

8 : 100

x : 125

100 x = 8 * 125

100x = 1000

x = 1000 / 100

x = 10

this month the spider ate 10 bugs
