Reggie, Andy, Julian and George paid a total of $198 for a present. George paid ⁴₇ of what the rest paid. Reggie paid 50% of what the rest paid. Andy and Julian paid an equal amount of money. How much did Julian pay?

Reggie	Andy	Julian	George	Total
7x3			4x3	11x3
1x11	2x11			3x11
	1	1
11 u	5 u	5 u	12 u	33 u

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

The total amount paid for the present is repeated.  Make the total amount the same.  LCM of 11 and 3 is 33.

Amount that Andy, Julian and George paid = 22 u

Amount that Andy and Julian paid
= 22 u - 12 u
= 10 u

The amount that Andy and Julian each paid is the same.

Amount that Andy and Julian each paid
= 10 u ÷ 2
= 5 u

Cost of the present = 33 u

33 u = 198

1 u = 198 ÷ 33 = 6

Amount that Julian paid
= 5 u
= 5 x 6
= $30

Answer(s): $30
