Question: Mario's salary increased by 40% to $4000 this year. Bob's salary from last year was equal to three times Mario's salary this year. If Bob's current salary is 20% more than his salary last year, what is his current salary? Think carefully first, then make a decision:
Last year, Bob's salary was equal to three times Mario's salary this year, meaning Bob was earning 3 * $4000 = $12000. If Bob's salary increased by 20% this year, he is earning 20 / 100 * $12000 = $2400 more. Bob's total salary this year is $12000 + $2400 = $14400. So the answer is 14400.
