If the candy is $4.50 per pound, Sami and her friend spent $ 18 altogether.
Solution:
Given that, Sami and her friend went to the candy store.
Each of them purchased a bag of jelly beans
Weight of sami bag = 1.5 pound
Weight of her friend bag = 2.5 pound
Cost of candy per pound = 4.50
We have to find how much did they spend altogether
Total weight of candy = Sandra bag weight + her friend bag weight
= 1.5 + 2.5 = 4 pounds
Total cost = number of pounds x 4.5 per pound
Hence, they spent $ 18 altogether.
