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.
