So, the best way to solve this problem is by creating a equation for which we can substitute any number of days. For this problem that equation would be W=5+3 (t-1)

W=number of words

T=time or number of days

-1 = This is here because we are already accounting for the first day of school so we need to have 1 less day than the number of days they have been in school.

So in 20 days the students had received

5+3 (19) or 62words.

Answer: 62 words
