A) 50 cans
1) We can write the sequence of collecting cans like this for Erica:
[tex](5,10,15,\ldots\text{.)}[/tex]2) Note that this is an Arithmetic Sequence and this can be described by the following explicit formula since the common difference is 5, the first element is 5:
[tex]a_n=5+(n-1)d[/tex]3) So let's find out the tenth term of that sequence
[tex]\begin{gathered} a_{10}=5+(10-1)5 \\ a_{10}=5+(9)5=50 \end{gathered}[/tex]Hence, on the tenth day She will collect 50 cans
