we are given

Takuya's parents gave him $100

so,

total money =$100

he spent $20 out of his present on board games at the end of each month

It means that

money spent in 1 month is $20

Let's assume he takes 'x' months

so, total money spent = money spent in 1 month* total number of months

so, we get

total money spent =
20*x

total money spent =
20x

now, we can set it to 100


20x=100

now, we can solve for x

divide both sides by 20


(20x)/(20) =(100)/(20)


x=5

so, total number of months is 5 .............Answer
