I think your question isn’t phrased well
Assuming he had not dealt with the bank offering plan B before, he has nothing deposited two years back. Hence plan B only gives him only 0.2% annual interest for his deposit.
Plan A gives 0.25% for his deposit all the time.
So plan A is more advantageous.
For durations,
To reach $1,000,000 from $100,000, the money needs to grow 10 fold, or
(1+i)^n=10
n=log(10)/log(1+i).
So for plan A:
n=log(10)/log(1.0025)=922.18 years, while for
plan B
n=log(10)/log(1.0020)=1152.44 years.
Hope the bank(s) still exist at that time.
Answer:
1 tens 3 ones
Step-by-step explanation:
All you do is count the numbers in the place value chart.
Since 31-18=13, all you do is count 10+1+1+1=13.
The median is 12.
The arithmetic mean is 12.7
The geometric mean is 11.3
