At a souvenir shop, all posters are priced equally and all maps are priced equally. What is the total price of 8 posters and 6 maps at the souvenir shop?

Questions: 8p + 6m = ?

(1) At the souvenir shop, the total price of 4 posters and 3 maps is $39.70 --> 4p + 3m = 39.70 --> multiply by 2: 8p + 6m = 2*39.70. Sufficient. (2) At the souvenir shop, the total price of 12 posters and 9 maps is$119.10 --> 12p + 9m = 119.10 --> multiply by 2/3: 8p + 6m = 2/3*39.70119.10 . Sufficient.

This is such a classic GMAT question. It preys on our instinct to mark E by assuming that both conditions reduce to the same equation, not realizing that we don't really need the price of each poster or map.

Hindsight 20/20 though!

I just marked answer C and didn't realize that I can reduce the equation in each line to match the one asked in the question. Argh.
