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

Question

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?

Step-by-Step Solution

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 0.50.5 dollars.
    • There are 100 packets required.
  • Step 2: Determine the total cost:

We use the formula for total cost:

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

Substitute the given values into the formula:

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

Perform the calculation:

Total Cost=50 \text{Total Cost} = 50

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

Answer

\( 50
