Question

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?

Answer 1

Total purchased w/o tax: $8 +$5 + $15 = $28
He paid (w/tax) $29.82 so 
$ 29.82 - $28 = $1.82 (sale tax)

Now we need to find the sales tax rate:

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

Double check:

$28 *6.5 / 100  = $1.82

$28 + $ 1.82 =  $29.82 total amount he paid..

So the sales tax rate is 6.5%

Answer 2

Answer:

$1.82 or 6.5%

Step-by-step explanation:

Amount paid by Sam for Purchasing brushes =$ 8

Amount paid by Sam for Purchasing palette =$ 5

Amount paid by Sam for Purchasing oil paints =$ 15

Hence, the total amount to be paid by Sam= $8+$5+$15

Total amount to be paid by Sam=$ 28

Total amount paid by Sam= $29.82

Sales- tax paid by Sam= $29.82- 28

Sales- tax paid by Sam= 1.82

Rate of sales-tax=$\frac{1.82}{28}$× 100

Rate of sales-tax=6.5%

Hence, the correct answer is 6.5%
