Ricardo throws a stone off a bridge into a river below. The stone's height (in meters above the water), xxx seconds after Ricardo threw it, is modeled by

w(x)=-5(x-8)(x+4)w(x)=−5(x−8)(x+4 )w, left parenthesis, x, right parenthesis, equals, minus, 5, left parenthesis, x, minus, 8, right parenthesis, left parenthesis, x, plus, 4, right parenthesis

What is the maximum height that the stone will reach?

The answer is 270 cars.you can do this by making a proportional relationship. for instance, 200 is the whole we are using, so on a “number line” 200 would be over 100%. now, since he sells 35% more, add 35% to 100% to get 135% on the other side of the “number line” on the bottom half, leaving the top half empty.cross multiply 200 by 135 then divide by 100 to get your answer. i hope this , if it did, , if you don’t mind, giving me brainiest! 200/100% } 200 • 135 /100 ? /135%

Bwould be the answer
