His answer was wrong. The correct answer would be 129,000
Explain: 500 rounded to the nearest thousand would be 1000
But 499 rounded to the nearest thousand would not become 1000

The marginal demand to estimate the change in demand when the price is increased by one dollar is -157.
Given,
where p represents the price of the item in dollars.
Currently, the price of the item is $20.
<h3>What is marginal demand?</h3>
In economics, marginal demand refers to the shift in demand for a product or service in reaction to a price adjustment. Normally, as the price of a good or service rises, demand decreases, and vice versa, as the price of a good or service decreases, demand increases.
We have to use the marginal demand to estimate the change in demand when the price is increased by one dollar.
The rate of change of demand with respect to price is obtained by differentiating D with respect to p in
.
That is, dD/dp = -8p+3
Given, p = $20
dD/dp = -8×20+3=-157
Therefore, the marginal demand to estimate the change in demand when the price is increased by one dollar is -157.

this is because if you multiply 5x3 your gonna get 15. 5x2 is 10 10/2 is 5 . hope this helps :).

we can eliminate the y terms by adding the equations
x-y=11
<u>2x+y=19 +</u>
3x+0y=30
3x=30
divide by 3
x=10
subb ack
x-y=11
10-y=11
minus 10 both sides
-y=1
times -1
y=-1
(x,y)
