Question

You have read 25 pages of a book. You plan to read an additional 10 pages each night. Write the explicit formula to represent the number of pages you will read after n nights.

Answer 1

Pages= 25 + 10n

Explanation:

Since the starting point is 25, that remains constant. 10n represents 10 pages per night.

Answer 2

p=10n+25

Explanation:

Let's have p represent the number of pages you will read. If you read 10 pages per night, then you are multiplying 10 by the number of nights, which gives you 10n. Because you have already read 25 pages, you want to add to the 10n to give you the equation of p=10n+25
