Answer:
$124.86
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.
