If X and Y are Boolean variables, then X + Y represents disjunction (OR) and XY represents conjunction (AND), and X' denotes the negation (NOT). So X + Y = 1 if either X = 1 or Y = 1, and XY = 1 only if both X = 1 or Y = 1.
Now,
(X + Y) (X + Y') = XX + YX + XY' + YY'
… = X + X (Y + Y') + 0
… = X + X
… = X

1755.97809915
1 cent is 1 hundredth of a dollar, so to round to the nearest cent means to round to the nearest hundredth.
The 7 in boldface is the hundredths place.
Drop all digits to the right of the 7.
1755.97
dropped digits: 809915
Look at the leftmost digit that was dropped (in boldface). If it is from 0 to 4, you are done, and the answer is 1755.97. If the leftmost digit that was dropped is from 5 to 9, the hundredths digit goes up by 1. Here, the first digit that was dropped is an 8, so the 7 in the hundredth place goes up 1 to 8.
Answer: 1755.98
