december, she saves $80 less than in
november. how much does she save
in all? use an equation to represent
the problem.

The total money saved by Juanita in all = $404

And the equation a   =  242 -  80 represent the problem.

Step-by-step explanation:

Here, the money saved in November by Juanita  = $242

Let us assume he money saved by her in December =$ a

Also, Money saved in December = Money saved in November - $80

⇒$ a   =  $242 - $ 80

or , a = $162

So, the money saved in December by Juanita  = $162

Now, the total savings = Money Saved in (November + December)

                                       = $242 + $162 = $404

Hence, The total money saved by Juanita in all = $404

And the equation a   =  242 -  80 represent the problem.
