Which inequality represents the sentence given? The difference of a number and one and four tenths is more than nine and seventy-eight hundredths.

“The difference of a number and 1.4” means subtract 1.4 from the number, giving p − 1.4. “Is more than 9.78” means the result is greater than 9.78. So the inequality is p − 1.4 > 9.78, which is choice C.
