Reggie read a 400- page book in 5 days. On the first day, he read 120 pages .each day after that , he read the same number of pages , show your work mathematics

Answer 1

400 pages in 5 days
but 120 on the first day
so 400-120=280
280 is what he read in the 4 days following
so divide 280 equally among the 4 days
You get 70 per day after the first

Answer 2

Answer:

Hence, Reggie read 70 pages per day after the first day.

Step-by-step explanation:

We are given that Reggie read a 400-page book in 5 days.

on the first day, he read 120 pages.

after first day he read the same number of pages.

Let Reggie read 'x' number of pages per day after the first day.

that means he read 4×x pages in remaining '4' days.

total number of pages=400

⇒   120+4×x=400

⇒     4×x=400-120

⇒      4×x=280

⇒       x=(280/4)

⇒        x=70

Hence, Reggie read 70 pages per day for four days after the first day.
