Glen, Jenson, Gabriel and Mark paid a total of $351 for a gift. Mark paid ⁴₉ of what the rest paid. Glen paid 50% of what the rest paid. Jenson and Gabriel paid an equal amount of money. How much did Gabriel pay?

Glen	Jenson	Gabriel	Mark	Total
9x3			4x3	13x3
1x13	2x13			3x13
	1	1
13 u	7 u	7 u	12 u	39 u

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

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

Amount that Jenson, Gabriel and Mark paid = 26 u

Amount that Jenson and Gabriel paid
= 26 u - 12 u
= 14 u

The amount that Jenson and Gabriel each paid is the same.

Amount that Jenson and Gabriel each paid
= 14 u ÷ 2
= 7 u

Cost of the gift = 39 u

39 u = 351

1 u = 351 ÷ 39 = 9

Amount that Gabriel paid
= 7 u
= 7 x 9
= $63

Answer(s): $63
