Answer:
2400cm^2
Step-by-step explanation:
50 * 10 = 500
(40 * 30 / 2) * 2 = 1200
30 * 10 = 300
40 * 10 = 400
Now add them all together.
500 + 1200 + 300 + 400 = 2400
Answer:
$7812.5million
$7812.5million
Step-by-step explanation:
From the question, the demand quantity <em>D(x) is 410-x </em> and the supply quantity <em>S(x)=160+x.</em> We determine the equilibrium quantity by equating the Demand quantity and the Supply quantity i.e
<em>D(x)=S(x). </em>
<em></em>
Hence the equilibrium quantity is 125.
Next we determine the equilibrium price. This can be obtain by just substituting the equilibrium quantity into either the demand quantity or the supply quantity. I prefer using the Demand quantity.
Equilibrium price=.
Next we write the expression for the Consumer Surplus
where <em>p</em> and <em>q </em> are the equilibrium price and equilibrium quantity respectively.
By substituting values we have
By carrying out simple arithmetic we arrive at
.
To determine the producer surplus, we use the expression below
Hence if we substitute values we arrive at
.
By simply simplification we arrive at

Answer:
- 80 restaurant purchased meals are eaten in a restaurant
- 31 meals are eaten in a car
- 60 meals are eaten at home
Step-by-step explanation:
Let us suppose r be the total number of meals eaten in a restaurant
Let us suppose c be the total number of meals eaten in a car
Let us suppose h be the total number of meals eaten in a home
- The total number of meals eaten in a restaurant, in a car or at home is given as 163. Hence,
- The total number meals eaten in a car or at home exceeds the number eaten in a restaurant by 11. Hence,
- Twenty more restaurant-purchased meals will be eaten in a restaurant than at home. Hence,
Substituting Equation [B] into [A],
Putting in
Putting and in
Therefore,
- 80 restaurant purchased meals are eaten in a restaurant
- 31 meals are eaten in a car
- 60 meals are eaten at home
Verification:
Putting , and in
