Step-by-step explanation:
What exactly is the question here?
The big bag is 16 ounces and $4.32
The medium is 20 ounces and $2.60
The small is 6 ounces and $1.80
So you want height to be 0 so you plug zero into the height and solve from there. You subtract 192 from both sides to get -192=-16tsquared. Then you would divide by -16 and end up with 12 = t^2. Then you find the square root of 12 and get t = 3.464 seconds.
