Answer:
$1.004 so rounded it would be Answer D ($1.00)
Explanation:
You multiply $25.10 by the decimal form of 4 percent, which gives you the tax.
25.10(.04)=1.004
1.004 is the tax, but with the way currency work, cents do not go to the thousandths place , so you round it to $1.00.
Incase you woudl also like to know, if you add that 1 dollar to the original price you get teh total price. which woudl be $26.10.
