Question 1155526
<font color=black size=3>
P = 10000 is the amount borrowed (principal)
r = 0.10 is the interest rate in decimal form
t = 1/2 = 0.5 is the time elapsed in years


i = P*r*t  is the simple interest formula
i = 10000*0.10*0.5
i = 500


Answer: <font color=red>500 dollars</font> 


Side note: P+i = 10000+500 = 10500 dollars is ultimately paid back in total, since you must pay back the principal on top of the interest. Though the question is asking about the interest paid only.
