Answer:
$1,050
Step-by-step explanation:
since these three transactions involved capital gains or losses (investments lasted more than 1 year), they will be taxed using the capital gains tax rate = 15%
total capital gains = $3,000 (painting) + $5,000 (stocks) - $1,000 (other stocks) = $7,000
total taxes due = $7,000 x 15% capital gains tax rate = $1,050
