Answer: $0.84 or 84 cents
Explanation:
Peter paid $12.83 for a DVD even though the price of the DVD player was $11.99.
To get the amount of sales tax Peter paid, we would subtract the price of the DVD player from the price paid by Peter. This will give:
=$12.83 - $11.99
= $0.84
Since 100 cents make a dollar, this will be: $0.84 × 100
= 84 cents
