Daniel's and Gillian's monthly allowances were the same at first. Daniel's allowance increased by 30% while Gillian's decreased by 25%. Given that Daniel's allowance would increase by another 10% if he had received $260 more from his Fathers, find the difference in the children's monthly allowances.

	Daniel	Gillian
Before	1 u	1 u
Change 1	+ 0.3 u	- 0.25 u
After 1	1.3 u	0.75 u
Change 2	+ 0.13 u	No change
After 2	1.43 u	0.75 u

Increase in Daniel's allowance
= 30% x 1 u
= ³⁰₁₀₀ x 1 u
= 0.3 u

Decrease in Gillian's allowance
= 25% x 1 u
= ²⁵₁₀₀ x 1 u
= 0.25 u

Increase in Daniel's allowance if his Fathers gave another $260
= 10% x 1.3 u
= ¹⁰₁₀₀ x 1.3 u
= 0.13 u

0.13 u = 260

1 u = 260 ÷ 0.13 = 2000

Difference in the allowance between Daniel and Gillian
= 1.3 u - 0.75 u
= 0.55 u
= 0.55 x 2000
= $1100

Answer(s): $1100
