Answer:
[tex]x + 4[/tex]
Step-by-step explanation:
The question have missing details.
Because, the question says she collected some cans "after picnic"; This means that she has some cans "before picnic"
So, we assume that she has x bags of can before the picnic.
[tex]After\ Picnic = 4[/tex]
So, the total number of bags collected is:
[tex]Total = Before + After\ Picnic[/tex]
[tex]Total = x + 4[/tex]
If x is 5, then she took 9 bags of can to the recycling center
If x is 2, then she took 6 bags of can to the recycling center
If x is 0, then she took 4 bags of can to the recycling center
