Which question? 21 or 22?
The more items sold the more profit they make
Amount of commission received by Steve for the first 4 sales of the month = $500
Amount of commission received by Steve for the next 6 sales of the month = $600
Amount of commission made by Steve
for the first 10 sales of the month = (500 + 600) dollars
= 1100 dollars
Average commission received by Steve per sale during the month = 1100/10 dollars
= 110 dollars
So the average commission received by Steve for a single sale during the month is $110. I hope the procedure is clear enough for you to understand.
V^2 = u^2 - 2gh; where v is the final speed, u is the initial speed, g = 9.8 m/s = 0.54 ft/min is the accerelation due to gravity, h = height.
At the maximum height, the final speed is 0.
u^2 = 2gh = 2 x 0.54 x 36 = 38.58
u = sqrt(38.58) = 6.21 ft/min
Therefore, the stne should be thrown with 6.21 ft/min
