Amount of purchase that Steve made = $40 Percentage of tax that Steve needs to pay = 10% Then Amount of tax that Steve needs to pay for the purchase = (10/100) * 40 = 1 * 4 dollars = 4 dollars Then The total amount including tax that Steve needs to pay for the purchase = (40 + 4) dollars = 44 dollars
So the dollar amount of tax that Steve had to pay is $4 and
the total amount that Steve had to pay was $44.
