It seems like the equation provided is incomplete. In order to find a specific value, we need more information.
If the equation is TC = 49 + 10x, where x represents the number of units produced, then we can find the total cost of making a certain number of units by substituting the value of x into the equation.
For example, if we want to find the total cost of making 5 units, we would substitute x = 5 into the equation:
TC = 49 + 10(5) TC = 49 + 50 TC = 99
Therefore, the total cost of making 5 units would be 99.
