1 answer

To determine how much Alexis owes after using a 20% off coupon, first, we need to calculate her total purchases before applying the coupon.

  1. Calculate individual costs:

    • Pack of markers: $2.50
    • Lunch box: $5.25
    • Two shirts: \( 2 \times 7.99 = 15.98 \)
  2. Calculate total cost before discount: \[ \text{Total cost} = 2.50 + 5.25 + 15.98 = 23.73 \]

  3. Calculate the discount amount: \[ \text{Discount} = 20% \text{ of } 23.73 = 0.20 \times 23.73 = 4.746 \]

  4. Calculate total after discount: \[ \text{Total after discount} = 23.73 - 4.746 \approx 18.984 \]

  5. Round to two decimal places: \[ \text{Total owed} \approx 18.98 \]

Thus, Alexis owes approximately $18.98.
