    Answer:

    2 $

    Step-by-step explanation:

    let the original price be x

    price after 10% discount = 3.60$

    x - \frac{10}{100} \times x = 3.60

    \frac{100x - 10x}{100} = 3.60 \\ \frac{90x}{100} = 3.60 \\ 9x = 36 \\ x = 4

    The original price of 2 pens is 4$

    original price of one pen = 4/ 2

    = 2 $
