Hãy xác định giá và lượng cân bằng của thị trường có ba hàng hóa với các hàm cung và hàm cầu của mỗi loại hàng hóa như sau:
- Hàng hóa 1: Qs1 = 3p1, Qd1 = 120 − p1 + p2 + 2p3
- Hàng hóa 2: Qs2 = −10 + 2p2, Qd2 = 150 + p1 − 2p2 + p3
- Hàng hóa 3: Qs3 = −20 + 5p3, Qd3 = 250 + 2p1 + 2p2 − 3p3

-4

step-by-step explanation:

the camry sales+accord sale=828,000. to make it so the two numbers are 18 thousand apart and still equal 828,000, you first need to find out what half of 828,000 is. 828,000/2=414,000. for the two numbers to equal 828,000, you have to add the same amount as you subtract from the middle. in this case, the number is 9,000 because it's half of 18,000. to equal 828,000, you have to add 9,000 to 414,000 for the camry and subtract 9,000 from 414,000 for the accord. 414,000+9,000=423,000.

414,000-9,000=405,000.

423,000+405,000=828,000.

423,000-405,000=18,

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950
