12 Joelle spent: Joelle's total = 1 : 2
Amount that Sabrina spent
= 3 x 1 u
= 3 u
Amount that the three girls spent
= 1 u + 3 u + 244
= 4 u + 244
Amount that the three girls spent
= 1432 - 436
= $996
4 u + 244 = 996
4 u = 996 - 244
4 u = 752
1 u = 752 ÷ 4 = 188
Amount that Abi and Sabrina had in the end
= 436 - 1 u
= 436 - 1 x 188
= 436 - 188
= $248
Answer(s): $248
