Final answer:
The expression that represents the total cost of an order of n number of concert tickets, each costing $35, with a $15 processing charge per order, is T = 35n + 15.
Step-by-step explanation:
To write an expression that represents the total cost of an order of n number of tickets to a concert, we take into account the price per ticket and the processing charge per order. The price per ticket is $35, and there is a flat processing charge of $15 for the entire order, regardless of the number of tickets purchased.
The total cost (T) can be expressed as:
T = 35n + 15
Where:
- n is the number of tickets ordered
- 35 is the cost per ticket in dollars
- 15 is the processing charge per order in dollars
This equation will give you the total cost of an order for any number of tickets you wish to purchase.
