Each mp3 sells at $120 per mp3 player multiply that by 100 its $12000
It cost them $45 per mp3 to be made multiply that by 100 its $4500 then add the $1500 for the week and its $6000

Step-by-step explanation:
Longest side is between 36 and 18 feet
18 < L < 36
IF longest side were 36 feet, width =0
IF longest side were 18, then width = 18
to be longest L>W L>18. and L can't be as much as 36 to keep width >0
Volume = length * width ( aka base ) * height
2 feet = 24 inches.
24*15*8=2880 inches.
Answer:
$290
Step-by-step explanation:
We are told that 1 out of 5 buyers change to a more expensive sofa than the one in the sale advertisement.
Now we are told that the advertised sofa is $250 and the more expensive sofa is $450.
Thus;
P(x) for expensive sofa = 1/5
P(x) for sofa in sale advertisement = 4/5
Thus, expected value is;
E(X) = (1/5)450 + (4/5)250
E(x) = 90 + 200
E(x) = $290
