Answer: Lana is saving at the greater rate.
Step-by-step explanation:
Given : Lana puts $50 each week into her savings account.
From the graph of Eliana 's Account , the line is passing through (0,0) and (2,94).
Rate of change of a line = [tex]\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{94-0}{2-0}=\dfrac{94}{2}=47[/tex]
It means Eliana saves $ 47 each week [Since , y axis represents Total Savings and x axis represents Time ( weeks).]
Clearly , $50 per week > $47 per week
It means Lana is saving at the greater rate.
