Which expression shows the amount Mark spent at the movies?
Understand the Problem
The question is asking for an expression that represents the total amount Mark spent at the movies, which includes the price of his ticket (t) and the cost of popcorn and a drink ($11).
Answer
The expression that shows the amount Mark spent at the movies is \( 11 + t \).
Answer for screen readers
The correct expression is ( 11 + t ).
Steps to Solve
-
Identify the total cost components
Mark spends money on two things: a movie ticket, represented by $t$, and the popcorn and drink, which costs $11$. -
Combine the costs
To find the total amount Mark spent, we need to add the cost of the ticket to the cost of popcorn and drink.
The expression will be:
$$ \text{Total cost} = t + 11 $$ -
Select the correct expression
Looking through the provided options, we see the expression that represents the total amount spent:
$$ 11 + t $$
This is the same as $t + 11$ since addition is commutative.
The correct expression is ( 11 + t ).
More Information
This expression correctly captures both components of the total amount Mark spent: his ticket and the cost of popcorn and a drink.
Tips
- Confusing multiplication with addition: Some may mistakenly interpret the expression $11t$ as multiplying the ticket price by 11, which is incorrect since it's an addition problem.
