Answer: $ 3,360

Step-by-step explanation:

Given : The principal amount borrowed for loan : $P=\ \$14,000$

Time period : $t=4$

Rate of interest : $r=6\%=0.06$

The formula to calculate the simple interest is given by :-

$S.I.=P\times r\times t\\\\\Rightatrrow\ S.I.=14000\times4\times0.06\\\\\Rightatrrow\ S.I.=3360$

Hence, the interest due on the loan = $ 3,360
