Answer provided by our tutors
the total amount that Stephanie will spend this month is: $8 (for being member of the club) + x rolls by $3.50 each, that is
f(x) = 8 + x*3.5 will be the equation of the money that Stephanie will spend per month if she develops x rolls of films by the price of $3.50 each
in our problem x = 5 since she developed 5 films
f(5) = 8 + 17.5 = $25.5
Stephanie will spend $25.5 this month.
