the cost of one orange is $1.5
From the graph given, there is a proportional relationship between cost and number of oranges.
To obtain the unit cost. we find the constant of proportionality.
- y = kx ; k = proportionality Constant
Using the point(2, 3)
3 = 2k
k = 3/2
k = 1.5
Hence, the cost of one orange is 1.5
