Question

Janie's goal is to spend no more than

$13 each week on coffee. The graph
shows the amount she has spent on
coffee over the last several weeks.

Answer 1

Answer: Lily's statement is correct, Janie met her goal.

Explanation:

We will find the unit rate for the given graph. If it is less than or equal to $13, then Janie will have met her goal and Lily will be correct. If it's greater than $13, then she won't have made her goal and Louis will be correct.

To find this, we will divide the money spent by the weeks. We can use any clear coordinate point, I will use (8, 100), or 8 weeks and 100 dollars.

$100 / 8 weeks = $12.5 per week

Since $12.5 < $14, Janie has met her goal and Lily is correct.
