Answer for screen readers
The total cost for the purchased shirts is $2p$, where $p$ is the price of one shirt.
Steps to Solve
-
Identify the number of shirts purchased You are buying 2 shirts and receiving 1 shirt for free. This means the total number of shirts is: $$ \text{Total Shirts} = 2 + 1 = 3 $$
-
Define the cost of the shirts Let's assume the price of each shirt is $p$. Since you only pay for 2 shirts, the total cost is: $$ \text{Total Cost} = 2 \times p $$
-
Express the total cost in terms of shirt price The final expression for the total cost, while considering the free shirt, will be: $$ \text{Total Cost} = 2p $$
The total cost for the purchased shirts is $2p$, where $p$ is the price of one shirt.
More Information
This scenario illustrates a common marketing strategy where you buy a certain number of items and receive an additional item for free, highlighting the concept of discounts in retail. The overall expenditure only reflects the cost of the items you are paying for.
Tips
- Forgetting the free item: It's easy to mistakenly calculate the cost as if all three shirts were purchased, instead of recognizing that the third shirt is free.
- Assuming shirt prices: Without specific prices given, ensure to define them as variables (like $p$) when calculating total costs.
