Sarah is writing a story. She writes 5 pages every day, and she has already written 15 pages. Which of the following represents the number of pages y written after x days?



Answer :

Answer:

Step-by-step explanation:

The number of pages written after x days can be represented by the following equation:

y = 5x + 15

Here's why:

y: represents the total number of pages written (unknown quantity we want to find).

5: represents the number of pages Sarah writes each day (constant rate).

x: represents the number of days that have passed (unknown variable).

+ 15: represents the number of pages Sarah has already written (initial quantity).

This equation reflects that the total number of pages written (y) depends on two factors:

The number of days that have passed (x) multiplied by her daily writing rate (5 pages/day).

The number of pages she already had written (15 pages).

By adding these two quantities, we get the total number of pages written after x days.
