Elijah, Charlie, Neave and Lee paid a total of $99 for a souvenir. Lee paid ⁴₅ of what the rest paid. Elijah paid 50% of what the rest paid. Charlie and Neave paid an equal amount of money. How much did Neave pay?

Elijah	Charlie	Neave	Lee	Total
5x1			4x1	9x1
1x3	2x3			3x3
	1	1
3 u	1 u	1 u	4 u	9 u

50%= ⁵⁰₁₀₀= ¹₂
Elijah's share : Total share = 1 : 2

The total amount paid for the souvenir is repeated.  Make the total amount the same.  LCM of 9 and 3 is 9.

Amount that Charlie, Neave and Lee paid = 6 u

Amount that Charlie and Neave paid
= 6 u - 4 u
= 2 u

The amount that Charlie and Neave each paid is the same.

Amount that Charlie and Neave each paid
= 2 u ÷ 2
= 1 u

Cost of the souvenir = 9 u

9 u = 99

1 u = 99 ÷ 9 = 11

Amount that Neave paid
= 1 u
= 1 x 11
= $11

Answer(s): $11
