Answer:
<em>3.94 seconds </em>
Step-by-step explanation:
h = - 16t² + 248
If stone is dropped, then h = 0
- 16t² + 248 = 0
t² =
t = ±
t < 0 is a solution of equation, but not a solution of the task
t = ≈ <em>3.94 seconds</em>
4c + 3s = 14
6c + 2s = 14.75
Create a formula for each situation. c represents cones, s represents sundaes, the constant at the end represents the price. Solve using graphing, substitution, or elimination to find the price of each.
