Answer:
$8286
Step-by-step explanation:
Jeff must obviously repay the original $6000 loan, plus simple interest.
The formula for simple interest is i = prt, where p is the principal, r is the interest rate as a decimal fraction, and t is the time, in years. Here we have
i = $6000*0.127*3, or i = $2286.
Adding these two quantitites together, we get A = p + prt +
$6000 + $2286 = $8286
