kylie spends $5.50 on 4 notebooks and 2 pens, Chloe spends $3.75 on 4 notebooks and 2 pens. How much is in one notebook and one pen?

Answer 1

n = cost of 1 notebook

p = cost of 1 pen

Based on the wording of the question,

4n + 2p = 5.50 (Kylie)

4n + 2p = 3.75 (Chloe)

This cannot be right, because elimination gives the absurd result

0 = 5.50 - 3.75

There has to be something wrong with the wording of the question.
