At first, Tom, Tim and George had the same amount of money. After George spent some of his money, Tom spent ³₇ of his money and Tim spent ³₅ of his money, Tom had $66 more than Tim. In the end, the total amount of money the three boys had left was $484. How much money did George spend?

	Tom	Tim	George	Total
Before	7x5 =  35 u	5x7 = 35 u	35 u
Change	- 3x5 = - 15 u	- 3x7 = - 21 u	- ?
After	4x5 = 20 u	2x7 = 14 u		$484

The amount that Tom and Tim each had at first is the same.  Make the amount that they each had the same.  LCM of 7 and 5 is 35.

Amount that Tom had more than Tim in the end
= 20 u - 14 u
= 6 u

6 u = 66

1 u = 66 ÷ 6 = 11

Amount that Tom and Tim had in the end
= 20 u + 14 u
= 34 u
= 34 x 11
= $374

Amount that George had in the end
= 484 - 374
= $110

Amount that George had at first
= 35 u
= 35 x 11
= $385

Amount that George spent
= 385 - 110
= $275

Answer(s): $275
