The maximum amount of revenue the carnival can expect in the town in the 5th night is; $4746.093.
A geometric progression is defined as a sequence in which any element after the first is obtained by multiplying the previous element by a constant which is called a common ratio denoted by r.
For example, the sequence 1, 4, 16, 64,… is a geometric sequence with a common ratio of r = 4.
We are told that Revenue in the first night = $15000
Now revenue of new night is 75% of the previous night. Thus;
2nd night = 15000 × 75/100 = $11250
3rd night = $11250 × 75/100 = 8437.5
Therefore, the given geometric sequence is ;
15000, 11250, 8437.5 ...
First term; a = $15000
Common ratio (r) = 11250/15000 = 0.75
The formula for the nth term of a GP is given by ;
aₙ = arⁿ ⁻ ¹
Thus, revenue for the 5th night is;
a₅ = ar⁵⁻¹
a₅ = 15000(0.75)⁴
a₅ = 4746.093
We conclude that the revenue in the 5th night in two will be $4746.093.
