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.
