The total​ (after-tax) cost of a laptop computer is ​$1618.59. The local sales tax rate is 8.5​%. What is the retail​ (pre-tax) price?

To find the retail (pre-tax) price of the laptop, we can use the following formula:

\[
\text{Total Cost} = \text{Retail Price} \times (1 + \text{Sales Tax Rate})
\]

Given:
- Total cost (after-tax) = \$1618.59
- Sales tax rate = 8.5% = 0.085

Let $ P $ represent the retail (pre-tax) price. The equation becomes:

\[
1618.59 = P \times (1 + 0.085)
\]

\[
1618.59 = P \times 1.085
\]

Now, solve for $ P $ (the retail price):

\[
P = \frac{1618.59}{1.085}
\]

Let's calculate this.

\[
P \approx 1491.00
\]

Thus, the retail (pre-tax) price is approximately **$1491.00**.
