The price of a package of 4 pens is $8.00. The same pens are sold at $2.50 each. If Alex bought three packages of pens rather than buying 12 pens individually, the amount he saved on 12 pens is what percent of the amount he paid?
Correct answer: C. 25%
- A. 12%
- B. 20%
- C. 25%
- D. 30%
Explanation
To solve this problem, you need to understand the concept of percentage savings. First, calculate the cost of buying 12 pens individually: 12 pens at $2.50 each totals $30. Next, calculate the cost of buying 3 packages of 4 pens (12 pens total) at $8.00 per package: 3 packages cost $24. The savings from buying in packages is $30 - $24 = $6. The percentage saved is computed by dividing the savings by the package cost: ($6/$24) x 100% = 25%. Therefore, the correct answer is 25%. The other options represent incorrect calculations of the percentage saved based on the cost difference and the amount paid.
