How much does each copybook cost if David pays $72.50 for 50 copybooks?

• A. $1.25
• B. $1.45
• C. $1.55
• D. $1.75

Answer: (B)

To determine the cost of each copybook, you need to divide the total amount paid by the number of copybooks purchased. In this case, David spent a total of $72.50 for 50 copybooks. First, perform the division: \[ \text{Cost per copybook} = \frac{\text{Total cost}}{\text{Number of copybooks}} = \frac{72.50}{50} \] Now, carry out the calculation: \[ \frac{72.50}{50} = 1.45 \] This means that each copybook costs $1.45. The correct answer reflects the accurate division of total cost by the number of items, leading to the understanding that the cost per unit is essential in real-world budgeting and expense tracking.
