40% =
40100 =
25 Emily spent: Emily's total = 2 : 5
Amount that Abi spent
= 3 x 2 u
= 6 u
Amount that the three girls spent
= 2 u + 6 u + 205
= 8 u + 205
Amount that the three girls spent
= 1505 - 436
= $1069
8 u + 205 = 1069
8 u = 1069 - 205
8 u = 864
1 u = 864 ÷ 8 = 108
Amount that Betty and Abi had in the end
= 436 - 3 u
= 436 - 3 x 108
= 436 - 324
= $112
Answer(s): $112
