#SI =$12.75#


You need to use the correct formula to calculate simple interest.

#SI = (PxxRxxT)/100#

P= principal (starting amount)
R= rate of interest as a % - hence the '100'
T = time period, given in years
SI = simple interest.

#A = amount = P+ SI#

Now just substitute in the given values and calculate.

#SI = (255 xx 5 xx 1)/100#

#SI =$12.75#
