Problem

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.
\[
25 a+10 c-5=25(? \vee)+10(? \vee)-5
