Question

How do i do this please help

Answer 1

Time = 4 years

Explanation:

Simple interest (I) is calculated as

I =
`(PRT)/(100)` ( P is principal, R is rate of interest, T is time in years ) , then

5425 =
`(15500(8.75)T)/(100)` ( multiply both sides by 100 to clear the fraction )

542500 = 135625T ( divide both sides by 135625 )

4 = T
