Hi , so without using any device or thing to get the answer I think that 75×5 equals 375 , now I'm going to check my answer , my answer is correct .What I always do is add , so basically I did this 75+75+75+75+75 =375.
We solve the question as follows:
Simple interest=Principle×Rate×Time
Thus given:
p=$55000, R=2.5%, time= 1 year
thus
Interest=55000×0.025×1=$1375
To evaluate the amount required to keep up with the inflation, your interest rate should match the inflation rate otherwise prices are going up faster than the savings.
Required interest rate=55000×0.034×1=$1870
The buying power lost will be the difference between your required interest and actual interest.
Thus:
Buying power lost=1870-1375=$495
I think it’s (4,2), If not I am so sorry.
8(51) = 8(50 + 1) = 8(50) + 8(1) = 400 + 8 = 408
