Answer :
The model would be:
p = 3n + 5
where p = the number of pennies Savannah has and n = the number of days that have passed.
This model works because each day, Savannah gets three pennies, shown in the equation as "3n." The "+ 5" at the beginning is there because the problem states that Savannah starts with 5 pennies.
