Answer:
$700
Explanation;
Givern the following
Amount borrowed = $500 (Principal)
Rate = 16%
Time = 30months = 30/12 yrs
Get the interest
Interest = PRT/100
Interest = 500*16*30/12*100
Interest = 5*16*30/12
Interest = $200
Amount owed at the end of 30months = Principal + Interest
Amount owed at the end of 30months = $500 + $200
Amount owed at the end of 30months = $700
