Answer:
36 pages per day on average
Step-by-step explanation:
Calculate the average.
3 * 28 (The first 3 days of the week where Mike reads 28 pages per day) = 84
4 * 42 (The next 4 days where Mike reads 42 pages per day ) = 168
168 + 84 = 252
To find the average using this total, divide it by the total amount of days of reading (seven days in this problem).
252 / 7 = 36
