Hãy xác định giá và lượng cân bằng thị trường có ba hàng hóa hàm cung và hàm cầu của mỗi loại hàng như sau : hàng hóa 1 Qs1 =20p1 - p2 - 4p3 + 34, Qd1 = 112-10p+4p2+2p3
hàng hóa 2 Qs2 = -p1 + 8p2 - 5p3 + 92 , Qd2 = 123 + p1 - 7p2 +2p3
hàng hóa 3 Qs3 = - p1 - p2 + 6p3 + 69 , Qd3 = 86 + p1 + 3p2 - 2p3

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.
