Question 1153018
<font color=black size=3>
interest = 5% of 200 
interest = (5/100)*200 
interest = 0.05*200
interest = 10 dollars


You have to repay $10 in interest on top of the $200 loaned to you. In total, you have to pay back 200+10 = 210 dollars.


A shortcut is to multiply 200 by 1.05 to get 200*1.05 = 210. The 1.05 multiplier represents 
100% + 5% = 1.00 + 0.05 = 1.05
In other words, this represents a 5% increase.
