Multiplication with Money: Calculate Total Cost of 100 Chip Packets at $0.50 Each

A packet of potato chips costs half a dollar. A teacher buys enough packets for 100 students to have one each. How much did she pay in total?

To solve this problem, we need to calculate the total cost paid by the teacher for the packets of potato chips. Here's how we approach it:

• Step 1: Identify the given information:
• Each packet costs $0.5$ dollars.
• There are 100 packets required.
• Step 2: Determine the total cost:

We use the formula for total cost:

$\text{Total Cost} = \text{Cost per Packet} \times \text{Number of Packets}$

Substitute the given values into the formula:

$\text{Total Cost} = 0.5 \times 100$

Perform the calculation:

$\text{Total Cost} = 50$

Therefore, the teacher paid a total of $50$ dollars for all the packets of potato chips.
