Answer: No, the rates are NOT equivalent.
Step-by-step explanation: Given that Mia saves $28 in 8 weeks and her sister saves $18 in 24 days.
We are to check whether the rates at which each sister saves equivalent.
We know that
1 week = 7 days.
So. 8 weeks = 7 × 8 = 56 days.
So, the rate at which Mia saves is given by
[tex]r_1=\dfrac{28}{56}=\dfrac{1}{2}=0.5~\textup{dollar per day}[/tex]
and the rate at which her sister saves is given by
[tex]r_2=\dfrac{18}{24}=\dfrac{3}{4}=0.75~\textup{dollar per day}.[/tex]
Thus, the rates at which each sister saves are NOT equivalent.
