Answer:
A book has 234 pages.
Step-by-step explanation:
Total number of Pages = x
Pages read on Monday = 45
Pages read on Tuesday = (1/2) x
Pages read on Wednesday = 72
Solve for x,
We know from above that,
x = 45 + (1/2) x + 72
Multiply equation by 2, we get;
2x = 90 + x + 144
2x - x = 90 + 144
x = 234
Hence the total number of pages of the book are 234.
