Answer:
The cost of 50 pounds of beans is $40.
Step-by-step explanation:
First, we find the slope:
[tex]\frac{8-4}{10-5} = \frac{4}{5}[/tex]
Now we know can find the equation of the graph:
[tex]y=\frac{4}{5} x[/tex]
Instead of x, we can plug in 50:
[tex]y=\frac{4}{5} *50\\y=\frac{200}{5} \\y=40[/tex]
