Show answer & explanation
Correct answer: A
Solution: 1
Money spent on Monday to buy 10 items = A
Money spent on Tuesday to buy 13 items = A + 3B
Money spent on Wednesday to buy 12 items = A + 2B
Money spent on Thursday to buy 11 items = A + B
Money spent on Friday to buy 12 items = A + 2B
Hence, total money spent = A + A + 3B + A + 2B + A + B + A + 2B
= 5A + 8B
Average = (5A + 8B)/5
= A + 8B/5
