Question

jennifer is shopping with her mother they pay $2 per pound for tomatoes at the vegetable stand. find the constant of proportionality in this situation also write an equation to represent the relationship

Answer 1

Constant of proportionality = 2

A= 2n

Explanation:

jennifer pay $2 per pound for tomatoes at the vegetable stand

Amount spent for vegetables depends on the number of pounds bought.So it is directly proportional.

cost per pound is constant.

Cost per pound for tomatoes is $2

So constant of proportionality is 2

Let A be the amount spent and n be the number of pounds

The relation between A and 'n' is

A= 2n

Answer 2

One the first problem on finding the constant of proportionality in this situation the answer is 2. Below is the solution:

constant = unit rate
unit rate = $2/ poung
K = 2

For the second question, the equation is the below:

T = 2p or y = 2x
