Draw Rita's as 1 unit, and Tim's as 1 unit + $50.
Their total = 2 units + $50
Now Jack has half of their total, so draw Jack as 1 unit + $25
So total of Jack and Tim is
1 unit + $25 + 1 unit + $50
= 2 units + $75
Since Rita's is 1 unit, and she has ⅓ of Jack and Tim's total,
1 unit is ⅓ of 3 units
So this tells 3 units is the same as 2 units + $75
Which also means $75 = 1 unit
All 3 children = 4 units = $75 x 4 = $300
Their total = 2 units + $50
Now Jack has half of their total, so draw Jack as 1 unit + $25
So total of Jack and Tim is
1 unit + $25 + 1 unit + $50
= 2 units + $75
Since Rita's is 1 unit, and she has ⅓ of Jack and Tim's total,
1 unit is ⅓ of 3 units
So this tells 3 units is the same as 2 units + $75
Which also means $75 = 1 unit
All 3 children = 4 units = $75 x 4 = $300
