    Step-by-step explanation:

    The 20% discount amounted to ...

    0.20 * $42.00 = $8.40

    so the price before tax was ...

    $42.00 - 8.40 = $33.60

    The tax amount is 3% of this value, so is ...

    0.03 * $33.60 = $1.008 ≈ $1.01

    So the total price paid for the shirt was ...

    $33.60 + 1.01 = $34.61

    Randy paid $34.61 for the shirt after discount and tax.

    ___

    Alternate solution

    You can realize that the 20% discount means that Randy will pay 80% of the original price of the shirt. Similarly, the 3% added tax means Randy will finally pay 103% of the discounted price. Then the total price Randy pays is ...

    $42.00*0.80*1.03 = $34.608 ≈ $34.61
