Seth makes homemade granola bars and sells them at local events. The table shows the price he changes for different quantities of granola bars.

The price per granola bar is the same for each quantity purchased, so the relationship is proportional.

The constant of proportionality is 1.5.

Step-by-step explanation:

Step 1:

For the given problem, the price is y and the number of granola bars is x.

To determine the constant of proportionality, we divide the value of y with the value of x.

If all the values of constant of proportionality are the same, it is a proportional relationship.

Step 2:

Assume the constant of proportionality is k.

For 2 granola bars, k

For 4 granola bars, k

For 6 granola bars, k

For 8 granola bars, k

As all the values of k are the same, it is a proportional relationship and the constant of proportionality is 1.5.

step-by-step explanation:

mean or average is 40.6
