Answer: Jack Corp's D/E ratio is 0.67.
We follow these steps to arrive at the answer:
We begin with the DuPont Identity for Return on Equity (RoE)
Substituting the values from the question in the DuPont identity we get,
So,
Substituting the value of equity multiplier in the formula above we get,
Now,
So,
Now that we have the proportions of debt and equity to total assets, we can find the Debt Equity (D/E) ratio as follows:
Substituting the values we get,
