Respuesta :

Answer:

1.92

Explanation:

Using the compound interest formula

A= P [ (1-i)^n-1 (where A= 1,000,000, P= 6000, i= ?, n= 30)

1000000 = 6000 [ (1 - i)^30-1

1000000 = 6000 [ (1 - i)^29

1000000 = (6000 - 6000i)^29

1000000/6000 = (6000/6000 -6000i/6000)^29

= 166.66 = i^29

= 29✓166.66 = ✓i^29

= 1.92 = i
