Answer:

No she doesn´t.

Step-by-step explanation:

So in order to solve this you just have to create an inequality, x is the number of bills that ANdrea has so if she has enough bills she could buy the pair of shoes:

5x-25=y

If y>0 then she could buy her shoes:

5x-25=y

5(4)-25=y

y=-5

Since -5 is not greater than 0 then she can´t afford the pair of shoes.
