Plan A at 60 calls : 60*.25 + 25 = 15 + 25 = 40
Plan A is equal plan B at 60 calls
So if more than 60 calls the plan B will cost less than plan A
Answer: more than 60 calls
I need a better picture, it is hard to see..

Answer:
See below
Step-by-step explanation:
Vertical velocity will be affected by gravity in this scenario
df = do + vo t + 1/2 a t^2 do = original height = 4 ft a = -32.2 ft/s^2
<u>df = 4 + 89 t - 1/2 (32.2) t^2 df = height</u>
<u />
On the way up and the way down, the ball may reach height of 102.2125 ft :
102.2125 = 4 + 89 t - 1/2 (32.2) t2 re-arrange to:
-16.1 t^2 + 89t - 98.2125 =0
Use Quadratic Formula to find <u>t = 1.5 and 4.0 s </u>
