What was the total amount of postage required to mail n letters?
(1) n = 10
(2) Each of the letters required at least $0.32 postage.

Target question: What was the total amount of postage required to mail n letters?

When I SCAN the two statements, they both feel insufficient, AND I’m pretty sure I can identify some cases with conflicting answers to the target question. So, I’m going to head straight to……

Statements 1 and 2 combined
There are several scenarios that satisfy BOTH statements. Here are two:
Case a: There are 10 letters, add each letter requires $0.40 in postage. In this case, the answer to the target question is the total postage cost = (10)($0.40) = $4.00
Case b: There are 10 letters, add each letter requires $0.50 in postage. In this case, the answer to the target question is the total postage cost = (10)($0.50) = $5.00
Since we cannot answer the target question with certainty, the combined statements are NOT SUFFICIENT

Answer: E

Cheers,
Brent

If these are the choices I get:

(1) n = 10
(2) Each of the letters required at least $0.32 postage.

Then how am I supposed to answer?
