Question

contant of proportionality 1) bananas are $0.59 per pound a) what is the contant of proportionality?b) how much will 25 pounds of bananas cost?c)

Answer 1

We have that one pound of bananas cost $0.59. Let 'x' be the number of pounds and let 'y' be the total cost. Then, we can write the following expression:

$y=0.59x$

a)since x and y have a proportional relationship, the constant of proportionality is 0.59

b) To find out how much it will cost 25 pounds of bananas, we can make x = 25 and solve for y:

$\begin{gathered} x=25 \\ \Rightarrow y=0.59\cdot(25)=1.75 \\ y=14.75 \end{gathered}$

therefore, 25 pounds of bananas will cost $14.75
