Coffee cost $18.96 for 3 pounds was the cost of per pound of coffee let x be the number of pounds of coffee if i buy the total of the cost of expound draw a graph of the proportional relationship between the number of pounds of coffee and the total cost of you can use technology to do this work where can you see the cost per pound of coffee in the graph what is it

We know that 3 pounds of coffee cost $18.96. We can use the rule of three to find the cost per pound

This means that one pound of coffee costs $6.32.

Having this ratio of change, we can express a linear function that models this problem

The image attached shows the relationship between these two variables, which has a linear behaviour.

Where represents cost in dollars, and represents pounds.
