Answer:
Rate = 10%
Step-by-step explanation:
We are given with the following details.
Interest earned = $ 116.25
Principal = $ 1550
Interest Rate = r (say)
Time = 9 months
= 
We are asked to determine the rate of interest for which we can earn 116.25 interest. As we are not specifically given whether it is a compound or simple interest , we assume it to be simple interest and solve .
The formula for simple interest is given as



r=0.1
Hence the r = 0.1
Hence the rate of interest is 10%
Hello there!
So, first we need to:
0.122 / 1 (1,000 / 1000)
0.122 (1,000) = 122
1(1,000) = 1,000
They are both 2 factors so we have to divide it by 2
122 / 1000
122 ÷ 2 = 61
1,000 ÷ 2 = 500
Fraction becomes: - 61 / 500
It's basic steps
Good luck on your assignment and enjoy your day
