Answer
Answer (as printed): C
Explanation
Let the number of spectators on Monday, Tuesday and Wednesday be 2p, 3p and 5p, respectively. Let the price charged on Monday, Tuesday and Wednesday be 2q, 3q and 4q respectively. According to the question. 4q × 5p × 3p = 8800 20 pq – 9 pq = 8800 ⇒ 11pq = 8800 ⇒ pq = 800 Now, total amount earned on all three days = 4 pq + 9 pq + 20 pq = 4 × 800 + 9 × 800 + 20 × 800 = ` (3200 + 7200 + 16000) = ` 26400
