Step-by-step explanation:
The given equation or expression is used to determine the total cost of buying carnival tickets.
the total cost is y
Also from the expression the cost of a ticket is $2.5
and x represents the number of tickets
now say x=5, that is 5 tickets, then the cost of buying the 5 tickets is given as
y=2.5(5)
y=12.5
Hence the cost of 5 tickets is $12.5
