Josie bought 9 souvenirs during 3 days of vacation. After 4 days of vacation, how many total souvenirs will Josie have bought? Solve using unit rates.

Step-by-step explanation:

3 days =  9 souvenirs

That means, for each (1) day, Josie will have bought 3 souvenirs.

Essentially you're just multiplying by 3.

3 x 1 = 3

So, 3 x 4 = 12.
