Question

Antonia is keeping track of the number of pages she reads. She started the school year having already read 95 pages of her book, and she then reads 20 pages each day. The function for her total pages read is f(x) = 20x + 95. What do f(x) and x represent in Antonia's situation?

f(x) represents the number of days; x represents the total number of pages Antonia has read.
f(x) represents the total number of pages Antonia has read; x represents the number of days.
f(x) represents the number of pages Antonia reads per day; x represents the number of days.
f(x) represents the total number of pages Antonia has read; x represents the number of pages she reads per day.

Answer 1

f(x) represents the total number of pages Antonia has read; x represents the number of days

Answer 2

f(x) represents the total number of pages Antonia has read; x represents the number of days.

Explanation:

f(x) is equal to the answer, which means the total if the variable "x" in 20x+95,X is the days she readed, which is multiplied by the pages she reads every day, "+95" is the pages she already readed before the school year began
