$ 35750
ExplanationThe formula to calculate total cost is the following:
[tex]total\text{ cost =total fixed cost+total variable cost}[/tex]so
Step 1
in this case, the variable cost is the cost from the watches ( because it depends on the number of watches produced)
hence
a)let
[tex]\begin{gathered} variable\text{ cost=unit cost of watches*number of watches} \\ variable\text{ cost= 19.50}\frac{\text{ \$}}{unit}1500\text{ units} \\ variable\text{ cost= \$ 29250} \end{gathered}[/tex]and
[tex]fixed\text{ cost=\$ 6500}[/tex]b) finally, replace in the formula
[tex]\begin{gathered} total\text{cost=totalf}\imaginaryI\text{xedcost+totalvar}\imaginaryI\text{ablecost} \\ total\text{ costs=29250+6500} \\ total\text{ costs=35750} \end{gathered}[/tex]therefore, the answer is
$ 35750
