combining factors of production is the role of
the situation in economic where by a more valuable good is sold at a low price while less valuable good is sold at a higher price .how can we describe this situation in economic

A trade-off  is a situational decision that involves diminishing one quality, or property of a design in return for gains in other aspects.

what is the short run industry supply curves?
james
I think there' s a mistake. P = - 0.4 + 0.2Qs is the supply curve and not the demand curve. Am I correct?
Qs is quantity supplied
The
This is what I think
The
this eaquation is supply curve Qs=P-0.4 the relationship is positive when the price increase the Qs increase....
mukhtaar
since Qs is quantity supplied P= -0.4 + 0.2Qs =>P +0.4=0.2Qs =>P/0.2 + 0.4=Qs I made Qs the subject of the formula or equation. So your answer is correct
The
P = -0.4 + 0.2Qs is the same as P/0.2+0.4=Qs Price has a direct relationship with the quantity supplied i.e the higher the price the higher the quantity supplied. that is why it is +0.4(this is the quantity and it is postive) and P/O.2(is the price and it is positive).
The
For the demand equation let me give an example 0.2P-0.4=Qd. Here the P is postive(+0.2) and the quantity which is -O.4 is negative( because of the negative sign(-) there is an inverse relationship between price and quantity. For quantity demanded the higher the price the lower the quantuty.
The
It's how I understand it
The
0.2P-0.4=Qd. the equation is wrong because the price have direct ralationship Quantity demanded but the correct equation is-0.2P -0.4=Qd so the higher price the lower Quantity
mukhtaar
I think the relationship is inverse because of the negative sign(-)
The
ok You mean the price and quantity demanded should be negative(inverse relationship) for Qd and the price and quantity supplied should be postive(direct relationship) for Qs
The
thank you for the correction
The
yes because it got a positive gradient of +0.2
Michael
This is the mistake I found: "Since P is on the vertical axis, it is easiest if you solve each equation for P. The demand curve is then P = 8 – 0.5Qd and the demand curve is P = –0.4 + 0.2Qs. Note that the vertical intercepts are 8 and –0.4, and the slopes are –0.5 for demand and 0.2 for supply."
Valeria
dear price do not depend on quantity. rather quantity depends on price. so the equation should be Qty=0.2Px-0.4
Michael
please can someone generate supply equation for me
ok
Detto
Qs=f(P,Pr,G,E,Z,Pf,)
The
where p is price, Pr is price of related goods, G is goals of a firm E is supplier's future expectation of prices,Z is other related factors, Pf is cost of factors of production.
The
I think it's wrong
The
if Qd=90-p Qs=90+p
The
the coefficient of price must be positive since supply curve is positively slopping
Kotey
yes
The
it's true. thank you

welcome

what is equilibrium
it is that point where price is equal to output or rather a point where demand is equal to supply
Fung
it is a point where consumer get maximum satisfaction and producers maximise profit or minimise loss
Imtiyaz
thanks
Obed
supply equal demand in one point
Messi
it's a point where supply and demand meets/equal whether profit or loss
