Q=50-0.5 and tc = 50-40 q

To find the value of q in the equation tc = 50 - 40q, we can substitute the given value of Q into the equation and solve for q.

Given: Q = 50 - 0.5

Substituting Q into the equation:
tc = 50 - 40q
tc = 50 - 40(50 - 0.5)

Now, simplify the equation:
tc = 50 - 40(49.5)
tc = 50 - 1980

Solving further:
tc = -1930

Therefore, the solution for q is -1930.
