Michael is on page 28 of a 315-page book. He must finish the book within the next 14 days. He solved the inequality 28 + 14 p less-than-or-equal-to 315 to find the minimum number of pages he must read per day to finish the book on time. What error did Michael make when he wrote this inequality to model the situation?

A. He did not account correctly for the 28 pages already read and should have solved 14 p less-than-or-equal-to 315 + 28.

B. He did not recognize that 315 is not a multiple of 14 and should have solved 28 + 14 p less-than 315.

C. He did not make the variable the minimum number of pages and should have solved 28 + 14 p greater-than-or-equal-to 315.\

D. He did not use the correct value as the coefficient of p and should have solved 14 + 28 p less-than-or-equal-to 315.
