## Interest rate model

We employ a triple-slope interest rate model to determine the borrowing interest rate with detail below:

 Utilization Range Interest rate at min. range Interest rate at max. range m b 0% - 60% 0% 20% 1/3 0 60% - 90% 20% 20% 0 0.2 90% - 100% 20% 150% 13 -11.5
$Interest = m * utilization + b$
