Alright, lets gets started.
I suppose , we are asked to find simple interest for above question.
Principal P = $1,250
Rate r = 5.7 %
Time t = 4 years
The formula for simple interest = [tex] \frac{P*r*t}{100} [/tex]
Hence simple interest [tex] = \frac{1250*5.7*4}{100} [/tex]
Simple interest [tex] = \frac{28500}{100} [/tex]
Simple interest = 285 $
Hence interest earned is $ 285. : Answer
Hope it will help :)
