Jade, Anna, Kimberly and Xandra jointly contributed to the cost of a present for their colleague. Jade's contribution is ²₃ of the total contribution made by the four girls. The ratio of Xandra's contribution to the total of Anna's and Kimberly's contribution is 5 : 2. What is the total contribution by the four girls if Anna's contribution is ¹₆ of Kimberly's contribution and the total amount contributed by Jade and Xandra is $1197?

Jade	Anna	Kimberly	Xandra	Total
2x49	1x49			3x49
	2x7		5x7
	1x2	6x2
98 u	2 u	12 u	35 u	147 u

Working backwards.

Total amount that Anna and Kimberly had is the combined repeated identity.
LCM of 2 and 7 = 14

Total amount that Anna, Kimberly and Xandra had is the next combined repeated identity.
LCM of 1 and 49 = 49 

Total amount contributed by Jade and Xandra
= 98 u + 35 u
= 133 u

133 u = 1197

2 u = 1197 ÷ 133 = $9

Total contribution by the four girls
= 147 u
= 147 x 9
= $1323

Answer(s): $1323
