Answer:
Relationship is proportional ;
8 oranges
Step-by-step explanation:
Oranges (lb) 2 ___ 3 ____5 ___?
Price ($) __ 3 ___4.50___7.50_12
For proportionality :
Oranges = k * price
Where, k = constant of proportionality
2 = 3k
k = 2 /3
k = 0.666666
Using k :
Number of oranges at price = 4.50 should be:
0.66666 * 4.50 = 3
Number of oranges at price = 7.50 should be:
0.66666 * 7.50 = 5
Hence, relationship is proportional
Number of oranges at $12
0.66666 * 12 = 8
