y= -3 Your Welcome tell me if you got it right
Step-by-step explanation:
Answer:
A
Step-by-step explanation:
AE=EC
5x-10=2x+5
5x-2x=5+10
3x=15
x=5
First number: x = 19
Second number: Y = -5
x + 2y = 9
2x + y = 33
Step-by-step explanation:
1.) The average nightly ticket sales can be calculated as
Average sales = Average no. of customers per night x Charge per ticket
For the second night, we have
$1750 = (N)($7)
This gives us N = 250.
So, the average number of customers decreased as a result of the price increase.
To calculate the percentage change, we use the following formula:
% change = 
We have -17% change in the average number of customers the theater has each night. The negative sign indicates a decrease in the number, which is consistent with our calculations.
2.) % change in prices = 
Therefore, we have 40% change in the cost of ticket per person, which reflects an increase in the prices.
3.) Elasticity of Demand = 
Hence, we have
= -0.425
This stands consistent with the Law of Demand - as the price increases, the quantity demanded decreases.
4.) Market price is obtained by looking for a point where the quantity supplied equals the quantity demanded. From the table we see that at $75 price, there is a demand for 45,000 units of that product in that market, which the suppliers are willing to supply. Hence, that defines the market price for that product.
If a advertised sofa is $200 but the more costly sofa is $375, the average cost of such a sofa will be $200 is $243.75.
<h3>Define the term average of the number?</h3>
- An averaging is a single number calculated as the average of a set of numbers,.
- Typically calculated as the sum of a numbers divided by the total number of numbers in the set (the arithmetic mean).
You're planning to purchase a sofa from a furniture store that is having a sale on them.
Let x represent the sofa's price.
Advertised sofa's cost = $200
Expensive sofa's cost = $375
The advertisers are aware that when customers arrive at the store, one out of three switch to an expensive sofa that the one shown in the sale advertisement.
Average cost = 375 x 1/4 + 200 x 3/4
E(x) = 375 x 1/4 + 200 x 3/4
E(x) = 93.75 + 150
E(x) = 243.75
Thus, if a advertised sofa is $200 but the more costly sofa is $375, the average cost of such a sofa will be $200 is $243.75.
