A hot air balloon rose from ground level to 1000 feet in order to pass over a mountain. The balloon then descended 800 feet to a cruising height.

Which point is a representation of cruising height in feet?
Point A
Point B
Point C
Point D

200ft.

Step-by-step explanation:

It's 200ft because you just do 1000 - 800 = 200ft

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
