salvador wrote 20 letters to his friends each month for p months in a row. write an expression to show the total number of letters salvador wrote

Question

can you please please help me 

Answer 1

Let N = number of letters

 

Salvador wrote 20 letters each month for p months.  So think about how many letters he wrote after 1 month (20), after 2 months (40), after 3 months (60), and so on.  The way you figure out the number of letters is to multiply the number of months by 20, so the expression is 

 

N = 20*p

 

You can check by plugging in values like 1, 2, or 3 for p that this expression is correct.
