Welcome to the Problem of the Week (P.O.T.W.)!!!
Guess and Check #2
This week’s question is: Christian and Sam went to Myers’ Maison of Miscellaneous Matter. Christian needs to buy a mallet for his xylophone. He sees some for $5.00 but he doesn’t buy them because, being a superlative xylophone player, he knows that they are of inferior quality. He sees a superior one that costs more. His friend, Sam, needs a strong magnet for his science kit. Christian finds him one that costs $5.00 but, unfortunately, it is not strong enough. Needing to impress his science teacher, Sam buys a superior magnet. Sam’s magnet costs $7.00 more than Christian’s xylophone mallet. Together, the magnet and the mallet cost $23.00. What is the cost of Christian’s xylophone mallet? (4 marks) What is the cost of Sam’s magnet? (4 marks)
