Tai went to a shopping mall. He spent $25.75 on a chirt, $15.49 on a hat and $9.95 on a poster, before tax. tax was 8.25% on all purchase. What was the total cost of tai's purchases, including tax?
First you add all the prices. But the nwhy do you multiply it by 1.0825?
Once you add all of the items,get the total you multiply by 0.0825 and that figure has to be rounded to the nearest cent
and then you add that figure to the total cost of the items as tax. then you get a total plus tax. Once again attempt and i'll check
You do not multiply by 1.0825.
You multiply by 0.0825.
Reason: because you need to convert the 8.25% to a decimal.
1.0825 is adding the tax to the items and giving you the total in a quicker fashion. 8.25% is the same as .0825. they add the one at the beginning so you don't need to add the 8.25% to the total as an extra step in my earlier response . I hope that makes sense.
To calculate the total cost of Tai's purchases, including tax, we first add up the prices of the items before tax. Tai spent $25.75 on a shirt, $15.49 on a hat, and $9.95 on a poster.
$25.75 + $15.49 + $9.95 = $51.19
Next, we need to calculate the tax on the total purchase. The given tax rate is 8.25%, which means we need to multiply the total by 0.0825 to find the amount of tax.
$51.19 x 0.0825 = $4.22 (rounded to two decimal places)
Finally, to find the total cost including tax, we add the tax amount to the original total.
$51.19 + $4.22 = $55.41
Therefore, the total cost of Tai's purchases, including tax, is $55.41.
The reason we multiply the total purchase by 1.0825 is because 1 represents the original total cost without tax, and adding 0.0825 to it accounts for the tax amount.
