Answer:
The total cost of ordering 5 tickets is $102.75.
Step-by-step explanation:
Tickets to a science museum cost $19.95 each.
Let the number of tickets ordered be represented by = x
There is also a $3 charge for each order, no matter how many tickets are ordered.
So, the expression for the cost (in dollars) of ordering tickets is :

And the total cost if you order 5 tickets, we will put x = 5

= $102.75
