Given:
The price of bananas can be determined by the equation P=0.25n, where P is the price and n is the number of bananas.
To find:
The constant of proportionality
Solution:
We have,
[tex]P=0.25n[/tex] ...(i)
where P is the price and n is the number of bananas.
Price P is directly proportional to the number of bananas. So,
[tex]P\propto n[/tex]
[tex]P=kn[/tex] ...(ii)
Where, k is the constant of proportionality.
On comparing (i) and (ii), we get
[tex]k=0.25[/tex]
Therefore, the constant of proportionality is 0.25.
