Answer: Total supply is 64 thousand units
Explanation:
Firm A's supply is given by
[tex]Q_{A} = −2 + P[/tex]
[tex]Q_{A} = −2 + 44[/tex]
[tex]Q_{A} = 42[/tex] units
Firm B's supply is given by
[tex]Q_{B} = 0.5P[/tex]
[tex]Q_{B} = 0.5*44[/tex]
[tex]Q_{B} = 22[/tex] units
So, total supply of [tex]Q = 42 + 22 = 64[/tex] thousand units
