13O + 12A = ?

Statement 1
39O + 36A = 111
Given there's no bulk purchase discount. We can assume the rates to be proportional to the number of items
13O + 12 A = 37
Sufficient

Statement 2
3O + 2A = 7
If we multiply 6, we have 18O + 12A = 42
If we multiple by 13/3, we have 13O +26A/3 = 91/3 or 39O + 26A = 91
This doesn't give us info to calculate the rate of 13 oranges and 12 apples
Insufficient

Answer A
Bunuel
If no bulk purchase discount applies, what is the price of 13 oranges and 12 apples?

(1) The price of 39 oranges and 36 apples is $111.

(2) The price of 3 oranges and 2 apples is $7.

Hi Bunuel, why statement 2 is not sufficient- 3o+2a=7$ [here only one value satisfies i.e. a=2$ , o=1$. Once we have the cost for each orange and apple we can place in the question and get the same answer as 37$ ...Please clarify why A and not D

Because the prices don’t have to be integers, so infinitely many (o, a) pairs can satisfy 3o + 2a = 7.
