Irene had $3744 at first.
Step-by-step explanation:
Let Angie and Irene had the money initially = $a
At a shopping mall Angie spent money = $2595
Money left with Angie = $(a - 2595)
Similarly, Irene spent the money = $297
Money left with Irene = $(a - 297)
Money left with Irene was thrice as much as Angie,
(a - 297) = 3(a - 2595)
a - 297 = 3a - 7785
3a - a = 7785 - 297
2a = 7488
a =
a = $3744
Therefore, Irene had $3744 at first.
