Let's calculate how much for the $12 t - shirt after the discount.
First, convert 40% into a decimal,
[tex]40\% = 0.4[/tex]
Next, multiply the cost by the discount,
[tex]12 \times 0.4 = 4.8[/tex]
Lastly, subtract the amount discounted,
[tex]12 - 4.8 = 7.2[/tex]
~~
Now
Let's calculate the amount after the sales tax,
First convert 9% to a decimal,
[tex]9\% = 0.09[/tex]
Next, multiply the cost of the t - shirt by the sales tax,
[tex]7.2 \times 0.09 = 0.648 = 0.7[/tex]
Lastly, add the amount of sales tax to the price of the t - shirt,
[tex]7.2 + 0.7 =7.9[/tex]
~~
Answer : the t - shirt will be $7.90 after everything.
