Exercise 2.7.2: Proofs by cases - even/odd integers and divisibility. About Prove each statement. (a) If is an integer, then is odd. Solution (b) If integers and have the same parity, then is even. The parity of a number tells whether the number is odd or even. If and have the same parity, they are either both even or both odd. (c) If integers and where are consecutive, then they have opposite parity. (d) For integers and , if is odd, then is odd and is odd.

(2,20) means that the 2 is 2 hours and 20 is 20$. so there both 20$ for 2 hours only the same price. like it says. so, the dunk tank and the bounce house are the same price (20$) for the same amount of time (2 hours).

step-by-step explanation:

it will cost dollar $540

the living room is 3 which means if we divide 325/3 then we get $108

therefore if 1part of the living room cost $108 and 3 costed $325

then total 5part of the room will cost 5*108 which gives $540
