Answer :
Notice that even if no toys are manufactured, the cost would be $5800, and each toy increases the total cost by $15.
A) Therefore, the equation that models the total production cost is
[tex]\Rightarrow C=15n+5800[/tex]Where n is the number of manufactured toys.
The answer to part A) is C=15n+5800
B) In the equation above, set n=3050 and solve for C, as shown below
[tex]C=15(3050)+5800=45750+5800=51550[/tex]The answer to part B) is $51550
C) Set C=23050 and solve for n, as shown below
[tex]\begin{gathered} C=23050 \\ \Rightarrow23050=15n+5800 \\ \Rightarrow15n=17250 \\ \Rightarrow n=1150 \end{gathered}[/tex]
