4)) A group of neighborhood families are planning a trip to the museum. Tickets are \( \$ 25 \) for adults and \( \$ 10 \) for children. The group also has a coupon for \( \$ 5 \) off. The expression \( 25 a+10 c-5 \) represents the total cost for \( a \) adult and \( c \) child tickets. Monica is purchasing tickets for 5 adults and 9 children.
Evaluate the expression to find the total cost.
\[
\begin{aligned}
25 a+10 c-5 & =25(5)+10(9)-5 \\
& =\square+?-5
\end{aligned}
