4-25.
FOR THE BIRDS
When filling her bird feeder, Sonja noticed that she paid $27 for four pounds of bulk birdseed. "Next time, I'm going to
buy 8 pounds instead so I can make it through the spring. That should cost $54.
a. Does Sonja's assumption that doubling the amount of birdseed would double the price make sense? Why or why
not? How much would you predict that 2 pounds of birdseed would cost?
b. To check her assumption, she found a receipt for 1 pound of birdseed. She decided
to make a table, which is started below. Copy and complete her table or use
the 4-25 Spedent Tool (Desmos). Click in the lower right comer of the graph to
view it in t-screen mode Desmos Accessibility

c. How do the amounts in the table grow?
d. Does the table confirm Sonja's doubling relationship? Give two examples from
the table that show how doubling the pounds will double the cost
