Let the pre-tax subtotal be $$ x $$. The tax rate is $$ 6.5\% $$, so the total after adding tax is given by

$$
x \times (1 + 0.065) = x \times 1.065.
$$

We know the after-tax total is $$ \$777.45 $$. Therefore, we have:

$$
x \times 1.065 = 777.45.
$$

To solve for $$ x $$, divide both sides by $$ 1.065 $$:

$$
x = \frac{777.45}{1.065}.
$$

Calculating the division:

$$
x = 730.
$$

Thus, the pre-tax subtotal was $$ \$730 $$.
The pre-tax subtotal was \$730.
