where 
A is the total amount at the end of two years 
P is the loan
r is the rate of interest in decimal
t is Number of Time Periods 
n is the number of times interest is compounded per year
in this problem we have 
P=$702
r=6%=6/100=0.06
t=2 years
n=4
substitute the given values in the formula

therefore
the answer is
$790.80
