Steve paid 10% tax on a purchase of $40. Select the dollar amount of the tax and the total dollar amount Steve paid.

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.
