Explanation of Solution

When the price is $8, the total quantity demanded can be calculated as follows:

Total quantity demanded=Individual quantity demanded(T+D+R)=3+1+0=4.

Thus, the value of the total quantity demanded when the price $8 is 4 units.

When the price is $7, ‘R’ individual quantity demanded can be calculated as follows:

Total quantity demanded=Individual quantity demanded(T+D+R)12=8+2+RR=2.

Thus, the value of ‘R’ individual quantity demanded is 2 units.

When the price is $6, ‘T’ individual quantity demanded can be calculated as follows:

Total quantity demanded=Individual quantity demanded(T+D+R)19=T+3+4T=12.

Thus, the value of ‘T’ individual quantity demanded is 12.

When the price is $5, ‘D’ individual quantity demanded can be calculated as follows:

Total quantity demanded=Individual quantity demanded(T+D+R)27=17+D+6D=4.

Thus, the value of ‘D’ individual quantity demanded is 4.

When the price is $4, the total quantity demanded can be calculated as follows:

Total quantity demanded=Individual quantity demanded(T+D+R)=23+5+8=36.

Thus, the value of the total quantity demanded is 36.

Expert Solution
Check Mark

Explanation of Solution

When the price per candy is $5, then ‘D’ the least amount of quantity demanded is 4, ‘T’ demand is 17 and ‘R’ demand is 6.

When the price per candy is $7, then ‘T’ the least amount of quantity demand is 8, ‘D’ demand is 2 and ‘R’ demand is 2.

Subpart (c):

Expert Solution
Check Mark

Explanation of Solution

When the price of candy decreases from $7 to $6, then ‘T’ the demand increases by 4(128) , ’D’ demand increases by 1(32)   and ‘R’ demand increases by 2(42) . Therefore, ‘T’ quantity demanded increases when the price is lowered from $7 to $6.

Subpart (d):

Expert Solution
Check Mark

Explanation of Solution

When ‘T’ withdraws from the market, then there is less demand at each price level and it shifts the demand curve to the left.

If ‘D’ doubles his purchase at each price level, then it increases the demand and it shifts the demand curve to the right.

Explanation of Solution

If the price is fixed at $6 and the total quantity demanded increases from 19 to 38, then it changes the demand that results in the change in price.

There are three consumers in the market for potato chips; Don, Peggy, and Pete. The following table displays each consumers' demand schedule for potato chips. For each blank space, type in the correct answer (write your answer as a number). Price per bag ($) .25 .50 .75 1.00 1.25 1.50 Don's demand 7 6 5 4 3 2 Peggy's demand 10 8 6 4 2 0 Pete's demand 6 5 4 3 2 1 a) At a price of $0.75 per bag, the quantity demanded by the market is [Select] units of potato chips. b) Suppose that the price of potato chips is initially $0.75 and increases to $1.25. There is [Select] by the market that is equal to [Select] units of potato chips. c) Suppose that Pete decides to go on a diet and will no longer purchases potato chips at any price. In addition, after Pete has left the market, suppose that we observe that the quantity of potato chips demanded by the market is equal to 14 units. We can therefore infer that the market price is [Select]
