Modified Difference Concept (Internal Transfer: Big to Small)

Given: Bigger Change, Smaller Difference, from Big to Small, Change  < Difference

Given: Bigger Change, Smaller Difference, from Big to Small, Change > Difference

First
Payton had $28 more than Gordon.
After Payton gave $38 to Gordon, Gordon had 3 times as much money as Payton.
How much money did Payton have at first?

(After)
Gordon : Payton
= 3 : 1

New Difference = Old Difference Double (Change - Difference)
Change - Difference = $38 - $28 = $10

Difference = 3 -1 = 2 units
2 units = $28 + 2 × $10 = $48

Payton (Before) = 1u + $38 = $24 + $38 = $62
