how do you show work for this problem?
Bananas are $ 0.59/pound
a.What is the constant of proportionality?
b.How much does 25 pounds of bananas cost?


Sagot :

A) In this case, the constant of proportionality is $0.59, as this remains the same, regardless of the different quantities. 
B) For this, you simply have to multiply $0.59 by 25, giving you $14.75. 
If you are looking at this equation, it will be in the form of y=kx, where k and x are constants.
