Let f be the function with variable n, which gives the number of pictures left in the phone after deleting pictures for n-days.
So f(1) gives the number of photos left after 1 day of deleting photos
f(2) gives the number of photos left after 2 days of deleting photos
and so on.
f(1)=745-20
f(2)=745-20-20=745-20*2
f(3)=745-20-20-20=745-20*3
so clearly f(n)=745-20n
Answer:
the algebraic expression is f(n)=745-20n,
where n is the n'th day of deleting photos, and f is the number of photos left after n days of deleting.
