    amount at end of 3 years = 4000+960 = ...
I = PRT
960 = 4000(R)(3)
R = 960/12000 = .08 or 8%
had the interest been 9%
I = 4000(.09)(3) = 1080
take over

    I found this on a website called Brainly and I think it is very helpful:
A) At the end of 3 years the amount in the account = Principal + Interest
Amount = 4000 + 960 = 4960
Amount at the end of 3 years = $4960
b) Formula for Rate , R = 100I/(PT)
Where I = Interest = 960, P = Principal = 4000, T= Time = 3 years
R = (100 Γ 960) / ( 4000 Γ 3)
R = 8
Rate, R = 8% per annum.
c) If the rate was 1% more, R = 8 + 1 = 9% per annum
Interest, I = PRT/100
Interest, I = 4000 Γ 9 Γ 3 /100 = 1080
Amount in her account would have been = $4000 + $1080 = $5080
Amount more = $5080 - $4960 = $120
She would have had $120 more should the rate were 1% greater.

    this might sound like a dumb question, but does anyone know the formula for finding what the simple interest rate is? i mean percentage wise, how much the money would go up. i donβt know how exactly to describe it but nothing pops up on google. thanks
