Suppose a person standing atop a building 398 feet tall throws a ball upward. If the person releases the ball 4 feet about the top of the building, the ball's height h in feet, after t seconds is given by the equation h = -16++ 48t + 402. After how many seconds will the ball be 338 feet from the ground?​

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%
