Question

Mia saves $28 in 8 weeks. Her sister saves $18 in 24 days. Are the rates at which each sister saves equivalent?

Yes
No
There is no way to tell

Answer 1

The rate of which mia saves IS equivalent. But, her sisters isn’t since 24 divided by 18 is a continuous decimal which is 1.333333....

Answer 2

The answer is no

I just calculated rates for each sister by getting the total money saved and divided by number of weeks! In order to see how much money they are making each week.


This can be shown like this

28/8=3.5

18/24=.75

As you can see the rates are not the same
