Apply discounts sequentially: first 25%, then an additional 20% on the discounted price.<br><br>\\(\begin{aligned}<br>\text{After 25\% off} &= \$120 \times 0.75 = \$90<br>\\<br>\text{After additional 20\% off} &= \$90 \times 0.80 = \$72<br>\\<br>\text{Overall discount} &= \$120 - \$72 = \$48<br>\\<br>\text{Overall percentage discount} &= \frac{48}{120} \times 100\% = 40\%<br>\end{aligned}\\)<br><br>Final Answer: Final price \$72, Overall discount 40%
