Explanation:

Identify the given values and target

We are given:

• Original price of the jeans: \(P_0 = \$68\)
• First discount (sale): \(40\%\) off
• Second discount (coupon): \(20\%\) off the sale price
• Target: Find the final price before taxes.

Calculate the sale price after the first discount

Using the Multi-step Percent Problems knowledge point:

$$ P_1 = P_0 \times (1 - 0.40) $$

$$ P_1 = 68 \times 0.60 = 40.80 $$

Calculate the final price after the second discount

Using the Multi-step Percent Problems knowledge point:

$$ P_2 = P_1 \times (1 - 0.20) $$

$$ P_2 = 40.80 \times 0.80 = 32.64 $$

Answer:

• (A) $27.20
• (B) $32.64 (Correct answer)
• (C) $40.80
• (D) $54.40
