Which expression can you use to find the total price of 5 concert tickets?
Understand the Problem
The question is asking which mathematical expression represents the total cost for 5 concert tickets, considering 't' as the price of one ticket. The options provided are various expressions involving 't'.
Answer
The expression to find the total price of 5 concert tickets is \( 5t + 2 \).
Answer for screen readers
The closest expression that represents the total cost for 5 concert tickets is ( 5t + 2 ).
Steps to Solve

Understanding Total Cost Calculation
To find the total cost for 5 concert tickets, we multiply the price of one ticket, represented by $t$, by the number of tickets (which is 5). The equation can be expressed as:
$$ \text{Total Cost} = 5 \times t $$ 
Analyzing the Given Options
We need to evaluate the provided expressions to see which one correctly calculates the total cost. The options are:
 ( t + 10 )
 ( 5t + 2 )
 ( 5(t + 2) )
 ( t + 15 )
 Checking Each Expression

Option 1: ( t + 10 )
This does not represent the total cost because it only adds a constant to the price of one ticket. 
Option 2: ( 5t + 2 )
This seems to imply 5 tickets plus an additional cost of 2, which is incorrect for just the ticket prices. 
Option 3: ( 5(t + 2) )
This expression distributes 5 to both ( t ) and 2, leading to $5t + 10$. While it includes 5 tickets, it incorrectly adds $10. 
Option 4: ( t + 15 )
This expression adds a constant to the price of one ticket, so it is not correct as well.

Identifying the Correct Expression
The correct expression for the total cost of 5 tickets should just be $5t$. None of the options provided directly gives this, but option 2 (( 5t + 2 )) is the closest, assuming the additional cost is not included in the total of just the ticket prices.
The closest expression that represents the total cost for 5 concert tickets is ( 5t + 2 ).
More Information
This problem revolves around understanding how to express the total cost given a unit price and quantity. We learned that multiplying the ticket price by the number of tickets is fundamental in cost calculations.
Tips
 Misinterpreting the problem by adding constants when only multiplication is needed.
 Forgetting to multiply the ticket price by the total number of tickets.
