c) Counteroffer
Explanation:
A counteroffer determines this when an offer is being created for the purpose of the earlier offer by another person during the negotiation for creating the ending contract. To make the counteroffer is to reject the previous offer and is created under the terms of the counteroffer or there will be no contract.
Here according to the given scenario, Jack makes the offer in the condition that he needs only microwave, refrigerator, and window treatment and this will be a sale part. Now, Padilla who is selling the home is accepting the terms of Jack with the condition that the refrigerator will remain in the home. So, this case is called the counter offer. 
 
        
             
        
        
        
If you need to indicate the missing ammount of each letter in the grahp then it will be like follows:
 For the first case:
A = $9,600 + $5,000 + $8,000 = $22,600$22,600 + $1,000 – B = $17,000
B = $22,600 + $1,000 – $17,000 = $6,600$17,000 + C = $20,000
C = $20,000 – $17,000 = $3,000
D = $20,000 – $3,400 = $16,600
<span>E = ($24,500 – $2,500) – $16,600 = $5,400
</span><span>F = $5,400 – $2,500 = $2,900
</span>And now for the second case:
G + $8,000 + $4,000 = $16,000
G = $16,000 – $8,000 – $4,000 = $4,000$16,000 + H – $3,000 = $22,000
H = $22,000 + $3,000 – $16,000 = $9,000(I – $1,400) – K = $7,000(I – $1,400) – $22,800 = $7,000
<span>I = $1,400 + $22,800 + $7,000 = $31,200
</span>J = $22,000 + $3,300 = $25,300
K = $25,300 – $2,500 = $22,800$7,000 – L = $5,000
<span>L = $2,000</span>
        
             
        
        
        
Answer:
a. Negative slopes
Explanation:
A negative slopes indicate that there exist a negative relationship between price and quantity demanded of a particular good. This means that when price falls, more units of goods will be purchased by the consumer and vice versa.
A normal good is a type of good whose demand increases as a result of increase in consumer's income. In other words, the higher the income, the higher the quantity demanded of such good by the consumer and vice versa.
It follows that when there is an increase in wage or income of a consumer , more goods will be purchased by them except if there is an increase in the price of such good . When there is price increase for such good, consumer will switch to a substitute good.
