Final answer:
To find the total cost of the jacket including tax, multiply the price of the jacket ($37.00) by the sales tax rate (6% or 0.06) to get the sales tax amount ($2.22). Add this to the original price to get a total of $39.22.
Step-by-step explanation:
To calculate the total cost of the jacket including tax, you first need to figure out the sales tax. The sales tax rate is given as 6%, so you convert this percentage to a decimal by dividing by 100, which gives you 0.06. Next, multiply the price of the jacket, $37.00, by the decimal sales tax rate to find the amount of sales tax.
$37.00 × 0.06 = $2.22
Now, add the original price of the jacket to the sales tax to get the total cost:
$37.00 + $2.22 = $39.22
Thus, the total cost of the jacket including tax is $39.22, which corresponds to option D.
