A football club has a balance of $100 million. The club then sells 2 of its players at $10 million each, and buys 4 more at $15 million each. How much money is left in the club register in millions of dollars? Think carefully first, then make a decision:
The 2 players are sold for a total of 2 * 10 = $20 million. So the club has 100 + 20 = $120 million. The cost of buying 4 more players at $15 million each is 4 * 15 = $60 million. So the club now has 120 – 60 = $60 million. So, the answer is 60.
