$14
Explanation:
Simple interest can be calculated using below formula
I=PRT .................(1)
Where P= principal = $200
I= interest = 1%
T= time = 7 years
R= rate = 1% = (1/100) =0.01
Then substituting the given values into eqn (1)
I = (200× 0.01 × 7)
I =$14
Hence, she will her earn $14 of interest
