It is given that,
There are 75 tickets.
Cost of each ticket is $3.
To find M(t):
M(t) is nothing but the total amount of money tai receives from the ticket sale.
That is,
[tex]\begin{gathered} M\mleft(t\mright)=Numberoftickets\times\cos t\text{ of each tickets} \\ M(t)=N(t)\times C(t) \end{gathered}[/tex]Therefore,
[tex]\begin{gathered} M(t)=75\times3_{} \\ =225 \end{gathered}[/tex]Hence, M(t) = $225 .
