Conclusion: It can be concluded that some consumers will pay
"15 times" as much for convenience, since sales of this convenience food continue to rise.
Flaw: NOT "15 times"
Conclusion says that,
Fresh: $2/10P
Dehydrated: $3/P -> $30/10P
Therefore, $30/$2 = 15 times more expensive!
(B) Since fresh potatoes are 80 percent water, one pound of dehydrated potatoes is the equivalent of 5 pounds of fresh potatoes.
However, 1P Dehydrated : 15P Fresh
Let's recalculate based on the information in B,
Fresh: $2/10P
Dehydrated: $30/10*5 -> $30/50P -> $3/5P -> $6/10P
Therefore, $6/$2 = 3 times only more expensive NOT 15 times !
It is not 15times, only 3 times. Caught the flaw!
In A,
(A) Fresh potatoes bought in convenient 2-pound bags are about $1 a bag, or 2 1/2 times more expensive than fresh potatoes bought in 10-pound bags.
Conclusion says that,
Fresh : $2/10P
C Fresh: $1/2P -> $5/10P
Dehydrated: $3/P -> $30/10P
Therefore, $30/$5 = 6 times more expensive! yeah the flaw is caught. But why is this Answer choice not better than A?
This answer choice is comparing convenient stores fresh potatoes, not in general of fresh potatoes.
Therefore, B wins. B is better than A.
(C) Peeled potatoes in cans are also more expensive than the less convenient fresh potatoes.
OFS- Seriously, why peeled potatoes?
(D) Retail prices of dehydrated potatoes have declined by 20 percent since 1960 to the current level of about $3 a pound.
OFS
Fresh : $2/10P
Dehydrated: $3/P -> $30/10P
Therefore, $30/$5 = 6 times more expensive! yeah the flaw is caught. But why is this Answer choice not better than A?
OFS
(E) As a consequence of labor and processing costs, all convenience foods cost "more" than the basic foods from which they are derived
OFS- OK. Convenient cost more than basic, but it does not shows the "MORE" means what.
