Answer:

$124.86

Step-by-step explanation:

We can find the sale price by multiplying $129.99 by (1.00 - 0.15), or 0.85, which results in $110.49.

Similarly, the final new price is (1 + 0.13)($110.49) = $124.86.

This breaks down to 1.00($110.49) = $110.49 (the sale price before tax) plus 0.13($110.49) = $14.36 (the tax on $110.49).  Adding $110.49 and $14.36 together results in $124.86.
