Thank you.

5 units --> 84 + 36 = 120
1 unit --> 120 ÷ 3 = 40 (Blue at last)
40 + 36 = 76 (Blue in the end)

4u-1u=84+36
3u =120
1u=40

So at first, Blue marbles= 1u+36=76.

1 - 2/5 = 3/5 (remainder)
3/5 x $480 = $288
1 - 1/4 = 3/4 (spent on 4 blouses)
3/4 x $288 = $216 (4 blouses)
$216 / 4 = $54 (each blouse)

ans : $54

verykiasummy & SarCha,

Many thanks for your help!
