Question

The table below shows the cost of downloading songs from a website.

What is the constant of proportionality between the total cost and the number of songs?

Answer 1

0.38

Explanation:

We just have to find how much each song download cost by dividing number of songs with cost.

1.14/3= 0.38

we can check this by doing another number in the table

4.56/12= 0.38

It is the same so the answer is 0.38

Hope this helps
