40% =
40100 =
25 Emily spent: Emily's total = 2 : 5
Amount that Zara spent
= 4 x 2 u
= 8 u
Amount that the three girls spent
= 2 u + 8 u + 164
= 10 u + 164
Amount that the three girls spent
= 1806 - 492
= $1314
10 u + 164 = 1314
10 u = 1314 - 164
10 u = 1150
1 u = 1150 ÷ 10 = 115
Amount that Elyse and Zara had in the end
= 492 - 3 u
= 492 - 3 x 115
= 492 - 345
= $147
Answer(s): $147
