Answer:
Step-by-step explanation:
Let x = the number of pounds of oranges in the full box.
On a field trip, students ate 3/10 of a box of oranges. This means that the students ate 3/10 × x = 3x/10 pounds of oranges.
Altogether they ate 6 pounds of oranges. This means that
3x/10 = 6
3x = 6×10
3x = 60
x = 60/3 = 20
The full box contained 20 pounds of oranges
Each tenth of the model is 2 pounds because a tenth of 20 pounds is 20/10 = 2 pounds
