Archie, Ahmad, Brandon and Vaidev paid a total of $468 for a souvenir. Vaidev paid ⁶₇ of what the rest paid. Archie paid 50% of what the rest paid. Ahmad and Brandon paid an equal amount of money. How much did Brandon pay?

Archie	Ahmad	Brandon	Vaidev	Total
7x3			6x3	13x3
1x13	2x13			3x13
	1	1
13 u	4 u	4 u	18 u	39 u

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

The total amount paid for the souvenir is repeated.  Make the total amount the same.  LCM of 13 and 3 is 39.

Amount that Ahmad, Brandon and Vaidev paid = 26 u

Amount that Ahmad and Brandon paid
= 26 u - 18 u
= 8 u

The amount that Ahmad and Brandon each paid is the same.

Amount that Ahmad and Brandon each paid
= 8 u ÷ 2
= 4 u

Cost of the souvenir = 39 u

39 u = 468

1 u = 468 ÷ 39 = 12

Amount that Brandon paid
= 4 u
= 4 x 12
= $48

Answer(s): $48
