A certain store sold pens for $0.35 each and pencils for $0.25 each. If a customer purchased both pens and pencils from the store for a total of $1.60, what total number of pens and pencils did the customer purchase?	Choose the correct choice from the following choices:
A) 6
B) 9
C) 10
D) 11
E) 12
Answer: Algebraically, the question looks like this: 2.5 = 0.35x + 0.25y. There are six possible numbers of pencils that fit that requirement:   1 pen: $0.35 and 5 pencils for $0.25 each. That's 1 pens and 5 pencils for a total of 6 pens and pencils. Choice (6) is correct.
