Which equation correctly uses the law of cosines to solve for $y$?

$9^2=y^2+19^2-2(y)(19) \cos \left(41^{\circ}\right)$
$y^2=9^2+19^2-2(y)(19) \cos \left(41^{\circ}\right)$
$9^2=y^2+19^2-2(9)(19) \cos \left(41^{\circ}\right)$
$y^2=9^2+19^2-2(9)(19) \cos \left(41^{\circ}\right)$

Law of cosines: $a^2=b^2+c^2-2 b c \cos (A)$

The salesperson needs to sell $18,000 worth of merchandise to meet his goal of earning $3,000 in July, considering his base salary of $1,200 and earning an additional $1,800 from commissions. This is calculated based on his commission being 10% of his total sales.
