<em>Solution; Probability ≈ 0.3571</em>
The money collected during the second week was : 840
<h3>Determine the amount collected </h3>
Analysis:
Total number of persons.
number of persons that paid first week = 12
number that paid second week = 62 - 12 = 50
if each person is to pay 16.40, then 50 people would pay = 16.4 x 50 = 840 dollars.
Hence we can conclude that The money collected during the second week was : 840

The present dimensions are : length = 12 feet
width = 9 feet
Area = 12* 9 = 108 feet squared
If the dimensions are increased by x feet the dimensions are :
length = 12 + x
width = 9+ x
Area = ( 12+x)( 9+x)
new area = initial area * 2
( 12+ x)( 9+ x) = 2 * 108
12*9 + 12x + 9x + xx = 216
108 + 21 x + x^2 = 216
x^2+ 21x = 216-108
x^2 + 21x = 108
x^2 + 21x -108 = 0
let us plug a= 1 b= 21 c= -108 in quadratic formula
x= [-21 + / - ( 21^2 - 4* 1 * -108 )^(1/2 ]/ 2* 1
x= 4.27
Answer :
Both sides are increased by 4.27 feet .
