Question: 268
14. Four friends each pay $5 for a pizza every Friday night. If they were to start inviting a fifth friend to come with them and still bought the same pizza, how much would each person then have to pay?
- A. $1
- B. $4
- C. $5
- D. $25
Correct Answer: B
Explanation:
B Take this question in bite-sized pieces. If four friends each pay $5 for a pizza, the pizza costs 4 × 5 = $20. Therefore, if a fifth friend joins, then 5 × p = $20. Divide both sides by 5, and each friend pays $4. The correct answer is (B).
