Sam bought brushes for $8, a palette for $5, and oil paints for $15. He paid $29.82 in all. What sales-tax rate did Sam pay?

The total cost before tax was calculated as $8 + $5 + $15 = $28
He spent (including tax) $29.82, thus
$29.82 - $28 = $1.82 (sales tax)

To determine the sales tax rate, we can use the following calculation:

$1.82 / $28 * 100 = 0.065 * 100% = 6.5%

To verify:

$28 * 6.5 / 100 = $1.82

Adding that to $28 gives a total of $29.82 that he paid altogether.

Therefore, the sales tax rate is 6.5%

Answer:

$1.82 or 6.5%

Here’s an explanation step-by-step:

Cost of brushes bought by Sam = $8

Cost of palette bought by Sam = $5

Cost of oil paints bought by Sam = $15

Thus, the total amount payable by Sam = $8 + $5 + $15

Total amount owed by Sam = $28

Total amount Sam actually paid = $29.82

Sales tax levied on Sam = $29.82 - $28

Sales tax charged to Sam = $1.82

Sales tax rate = × 100

Sales tax rate confirmed as = 6.5%

Conclusively, the accurate answer is 6.5%
