Final answer:
The expression representing Marisa having $26 and paying $5 for lunch is $26 - $5. This subtraction will provide the amount of money she has left after buying lunch.
Step-by-step explanation:
Marisa has $26 in her purse. She pays $5 for lunch. The expression that represents this situation is $26 - $5.
To find out how much money Marisa has after paying for lunch, we start with the amount she has initially and subtract the cost of lunch. So, we take her starting balance of $26 and subtract the $5 she spent on lunch, which gives us the remaining balance.
Therefore, the expression we need is:
- $26 (starting balance) - $5 (cost of lunch) = Remaining Balance.
This is a simple arithmetic problem involving subtraction.
