Answer:
8.75%
Step-by-step explanation:
The formula for calculating simple interest (I) is
I = 
where P is the principal, R the rate of interest and T the time in years
here I = 350, P = 2000 and T = 2, hence
350 = ![\frac{2000(2)R[tex] = [tex]\frac{4000R}{100}](https://tex.z-dn.net/?f=%5Cfrac%7B2000%282%29R%5Btex%5D%20%3D%20%5Btex%5D%5Cfrac%7B4000R%7D%7B100%7D)
multiply both sides by 100
35000 = 4000R ( divide both sides by 4000 )
R = 8.75%
