The Lawrence company has a ratio of long term debt to long term debt plus equity of$\mathrm{.}4$ and a current ratio of $1\mathrm{.}2.$ current liabilities are $$960,$ sales are $$6380,$ profit margin is $9\mathrm{.}3\%$ and ROE IS $20\mathrm{.}1$ PERCENT. What is the amount of the firms net fixed assets?

$*$This is all of the information the question gives me$.$ I cannot figure out how to get long term debt, so I can figure out the net fixed assets. HELP!
