Answer:
(10+t)*25
Step-by-step explanation:
25 students so the cost for 1 student needs to be multiplied by 25 for all the students
If lunch costs $10 by itself not including the ticket, we don't know how much the ticket costs so lets say ticket cost = t
$10+t = the cost for ONE student
but there are 25 students so, ($10+t)*25 could work
Expressions don't have equal signs so the total is (10+t)*25
