Answer:
1. $224
2. She spent $224 in postage, but we don't know how much she spent in each souvenir.
Explanation:
Knowing that Rose visited 14 cities on her vacation and she bought 8 souvenirs in each city, she bought a total amount of 14x8 = 112 souvenirs. Rose paid $2 in postage for each souvenir, then she spent 2x112 = $224 to send all of the souvenirs.
