1)d. The quantity of a product that consumers are willing and able to buy at each unit price
2)C. The product has a lower price
3)c. The quantity demanded for chips will decrease and the demand for salsa will decrease.
4)I didn't understand your question about this one but I can explain the graph:-)
according to this diagram
the supply curve has shifted backward i.e supply is decreased so, with the decrease in supply the price of good increases and as a result of increased price the quantity demanded decreased.
5)B. Average consumer income has decreased, with Good A being an inferior good. ( because as you can see in the diagram that demand for good A is increased)
demand for inferior goods increases with the decrease in income. For example: if your income decreases you'll start travelling from bus instead of train.
6)B. Stacy wanted ice cream a bit more than a cupcake but chose the cupcake when the price of ice cream increased.
The mean for the total cost of the two items is 82. The standard deviation of the total cost of the two items is 14.14214. The probability of finding two random items at this auction with a total price of less than $80 is 0.44377.
<h3>What is a random variable?</h3>
A random variable is a variable with an undetermined value that gives values to each of the results of a statistical experiment.
From the parameters given:
- Let us assume that X represents the random variable that connotes the price of the item during the large auction.
Given that:
- X is normally distributed with a mean of $41 and
- A standard deviation of $10
X
N(μ, σ²)
X
N(41, 10²)
Suppose we made an assumption that Y should denote the total cost of items:
i.e.
Y = X₁ + X₂
Here;

The variance of (Y) is:


= 14.14214
The probability of finding the two random items at the auction with a total price of less than $80 can be computed as:
P(Y < 80)
Since the data is normally distributed,



Recall that:
P(Z < -z) = P(Z > z)
Hence;
= P (Z > 0.1414213)
= 1 - P(Z ≤ 0.1414213)
From the Z tables, the value of Z at 0.1414213 is 0.55623;
= 1 - 0.55623
= 0.44377
Therefore, we can conclude that the probability of finding two random items at this auction with a total price of less than $80 is 0.44377.

I may be wrong, but this is what I did:
8.9 x 10^5 x 2000 (1 ton is 2000 lbs) x 16 (16 ounces in 1 pound)
=2.848 x 10^10
