40000
Step-by-step explanation:
Simple interest (I) is calculated as
I = 
P is the amount borrowed , R is the interest and T the time in years
Here I = 2000 , R = 5 and T = 1 with P to be found , then
2000 = 
( multiply both sides by 100 )
5P = 200000 ( divide both sides by 5 )
P = 40000

Answer: 1.76
1.54
Step-by-step explanation:
we have to divide 800 by 453.592, and the result is 1.763699... rounding it: 1.76
now we do the same for 700 :
700 divided by 453.592 is 1.5432... so rounding it down: 1.54
