The amount that Neave had left is the same. Make the numerators the same. LCM of 5 and 10 is 10.
5x211x2 of his money =
1011 of his remaining money
1022 of his money =
1011 of his remaining money
Amount that Neave spent on the windbreaker = 11 u
11 u = 33
1 u = 33 ÷ 11 = 3
Amount that Neave had at first
= 22 u
= 22 x 3
= $66
Answer(s): $66
