Question

Kelli has already taken 20 pictures with her new cell phone. She plans on taking 15 pictures each day on her trip to the beach. Which function f(x) models the relationship between the number of days at the beach, x, and the total number of pictures f(x) on Kelli's phone?

Answer 1

1.

Explanation:

Answer 2

The relation is

f(x) = 15*x + 20

Explanation:

She has already taken 20 pictures of her phone. This represents an initial value.

Then for each number of days x, she will take 15 pictures per day

This means

15*x

If we add together, we get

f(x) = 15*x +20
