    Since the sales tax is 7%, that adds $10.50 to the bill, which is added up to $160.49, but since you said round up to the nearest cent, I'd say your answer should be:

    $160.50

    Total cost=original+tax

    tax=7% of 149.99

    tax=0.07 times 149.99

    tax=10.49993

    total cost=149.99+10.49993

    total cost=160.4893

    round

    TC=$160.49
