Oh this is easy

5,000x. 085=425

That is the amount he made in the year from intrest

Now cut that into a 4th

106.25

He makes 106.25 quarterly

Reece Jacobs · Answer 2

5000 (1+.085/4) ^n=1000

to find n use log:

1.02125^n

N X log1.02125

when computed=32.9

round to 33 quarters compounded

33/4

equals to 8 years 3 months
