If we multiplied by something like 0.001, we'd also be going two places, just going smaller and to the left.
Answer: 6 years
Step-by-step explanation:
Formula to calculate compound amount: , where P= Principal , r=rate of interest, t= time
Given: P = £400, r = 3% = 0.03 , A= 475
Required equation:
Taking log on both sides , we get
Hence, he needs to invest the money for 6 years to get atleast £475.
