30 percent change is the answer
Rate tables are useful because it has something that stands for something else. For example,
1)
a.
60 ounces = 3 pounds
So no, you don’t have as much fruit as you need.
b.
60 ounces —> 3 pounds
X ounces —> 4 pounds
Cross product :
(60 x 4) / 3 —> 240/3 = 80
So in order to have 4 pounds of fruits, you need 80 ounces of fruits.
You already have 60 ounces of fruits.
X + 60 = 80
80 - 60 = X
20 = X
You need 20 more ounces to have 4 pounds of fruits.
