Answer:
6.5%
Explanation:
Total cost before tax
= Cost of Brushes + Cost of Palette + Cost of paint
= 8 + 5 + 15
= $28.00
It is given that in total, he paid $29.82
Hence the amount he paid in taxes
= Total amount paid - total cost before tax
= $29.82 - $28.00
= $1.82
Therefore, sales tax rate
= (taxes / cost before tax ) x 100%
= (1.82 / 28) x 100%
= 6.5%
