Question

Princess Madeline arranges 8 magazines in the rack and Manny adds a few more. Bob takes away 9 magazines from the rack. Now there are only 8 magazines in the rack. How many magazines did Manny add?

• A. 8 magazines
• B. 10 magazines
• C. 7 magazines
• D. 9 magazines

Answer 1

The correct option is D 9 magazines

$\text{Detailed step-by-step solution:}$
Number of magazines Princess Madeline arranges in the rack = 8
Number of magazines finally left in the rack after Bob takes away 9 = 8
Number of magazines in the rack if Bob does not take any magazines = 8 + 9


Number of magazines added by Princess Madeline and Manny together = 17
Number of magazines Manny added = 17 – Number of magazines added by Princess Madeline = 17 – 8
We know that,
8 + 9 = 17
So, 17 – 8 =9
Therefore, Manny has added 9 magazines to the rack.
