Neave's and Pamela's monthly allowances were the same at first. Neave's allowance increased by 35% while Pamela's decreased by 25%. Given that Neave's allowance would increase by another 20% if he had received $378 more from his Mothers, find the difference in the children's monthly allowances.

	Neave	Pamela
Before	1 u	1 u
Change 1	+ 0.35 u	- 0.25 u
After 1	1.35 u	0.75 u
Change 2	+ 0.27 u	No change
After 2	1.62 u	0.75 u

Increase in Neave's allowance
= 35% x 1 u
= ³⁵₁₀₀ x 1 u
= 0.35 u

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

Increase in Neave's allowance if his Mothers gave another $378
= 20% x 1.35 u
= ²⁰₁₀₀ x 1.35 u
= 0.27 u

0.27 u = 378

1 u = 378 ÷ 0.27 = 1400

Difference in the allowance between Neave and Pamela
= 1.35 u - 0.75 u
= 0.6 u
= 0.6 x 1400
= $840

Answer(s): $840
