Question

Jenny read 12 pages on Monday, 25 pages on Tuesday and

the remaining pages on Wednesday. On average she read
23 pages per day during these three days. How many pages
did she read on Wednesday?​

Answer 1

32

Explanation:

Let Wed pages = x

(12 + 25 + x) / 3 = 23 Multiply both sides by 3

12 + 25 + x = 3 * 23 Combine the right

12 + 25 + x = 69

37 + x = 69 Subtract 37

x = 69 - 37

x = 32

32 pages were read on Wed
