Goose bought = 15 & Ducks Bought = 12 if a Chief steward spent $2,820 on buying 27 Birds each goose cost $140 and each duck Cost $60
Step-by-step explanation:
a Chief steward spent $2,820 on buying goose and ducks
Let say goose Bought = G
& Duck Bought = D
total of numbers of birds bought is 27
=> G + D = 27 Eq1
each goose cost $140 and each duck Cost $60
=> 140G + 60D = 2820
=> 14G + 6D = 282
=> 7G + 3D = 141 Eq2
Eq2 - 3 * Eq1
=> 4G = 60
=> G = 15
D = 12
Goose bought = 15 & Ducks Bought = 12
