Question

hi! can help us with this qn? Ans given was $126 which didnt seem right. Tq!

Answer

Scenario 1 : If Sylvia buys the blouse, the ratio of her money left to the amount of money Farah has will be 2 : 5,
Sylvia : 2u + 31.50
Farah : 5u

Scenario 2 : If Farah buys the blouse, the ratio of her money left to the amount of money Sylvia has will be 8 : 13.,
Sylvia : 13p
Farah : 8p + 31.50

2u + 31.50 ——-> 13p
10u ——-> 65p – 157.50
5u ——–> 8p + 31.50
10u ——-> 16p + 63
65p – 157.50 ——-> 16p + 63
65p – 16p = 49p ——-> 63 + 157 50 = 220.50
1p ——-> 4.50
13p ——-> 58.50

Ans : $58.50.

hi! thanks for the solution! may I check with u, based on my understanding, the ratio 8:13 refers to the amount of money Farah has left to the amount of money Sylvia has. and not the other way round?
