@zscdragon is god

camerondoherty · Answer

and yes @Arnab09

anonymous · Answer

so it is decreasing as it is getting multiplied by 0.63 repeatedly, which is less than 1

Thank you @Arnab09 and cn you help me ith part 2 of this question?

camerondoherty · Answer

and by how much is it decreasing exactly?

anonymous · Answer

if you are multiplying repeatedly by 0.63, how much is it decreasing per year?
say the amount is y
after one year it will be 0.63y
so decrease = y-0.63y=0.37y
so decrease per year= 0.37*100%=37%
