Half of Jerome's money was $43. He gave $8 to Meg and thrice as much to Bianca. How much does Jerome have left? Let's answer step by step:
Jerome has $43 x 2 = $86. After giving Meg $8, he had only $86 - $8 = $78 left. Then he gave Bianca $8 x 3 = $24. So, Jerome has only $78 - $24 = $54 left. The answer: 54.
