37 of Neave's money
1518 of Abi's money =
1535 of Neave's money
Amount that Abi had at first = 18 u
Amount that Neave had at first = 35 u
Amount that Abi had less than Neave had at first
= 35 u - 18 u
= 17 u
17 u = 1564
1 u = 1564 ÷ 17 = 92
Amount that Neave had at first
= 35 u
= 35 x 92
= $3220
Answer(s): $3220
