Step-by-step explanation:
2x +8y = 54
x + 9y = 67
x = 67 - 9y
2(67-9y) + 8y = 54
434 - 18y + 8y = 54
434 - 10y = 54
10y = 54 - 434
10y = -380
y = -38

Answer:
1.1%
Step-by-step explanation:
cost price=1.10×12
=$13.20
selling price=(12-3)×1.45
=9×1.45
=$13.05
loss= cost price-selling price
=13.20-13.05
=0.15
loss percent=0.15/13.20×100
1.13636
1.1%
