Kimora Patterson · Answer 1

Answer: 1.05%

Step-by-step explanation:

Principal = $30000

Time = 4 years

Rate = Unknown

Interest = 1260

Simple interest = PRT/100

1260 = (30000*R*4) / 100

Cross multiply

1260*100 = 120000R

126000=120000R

Divide both side by 120000

R = 126000/120000

R = 1.05%
