1. Figure out how much each of the 5 friends spent; assume it's 1/5 of the total, or $18/5, or $3.60 each. 2. Subtract the cost of 1 package of juice from this $3.60. Your result is the cost of a package of dried fruit.
Well I don't know if i'm answering the question, but 30 workers surveyed were satisfied with the benefits they received from the employers because 300 multiplied by .10 is 30. Hope my answer is useful.
