The seats in the theater follows the sequence given by:
7,9,11,..
This is an arithmetic sequence which follows an explicit formula given by:
an=a+(n-1)d
where:
a=first term
d=common difference
but
a=7 and d=9-7=2
thus
an=7+(n-1)2
an=7+2n-2
an=2n-5
Thus the number of seats in nth row is:
an=2n-5

\cos U = \frac{\text{adjacent}}{\text{hypotenuse}}=\frac{2.2}{4.7}
cosU=

\cos U = \frac{2.2}{4.7}
cosU=

U=\cos^{-1}(\frac{2.2}{4.7})
U=cos

U=62.09\approx 62^{\circ}
U=62.09≈62

It is $11.25 Per person
I believe. Because of the typing of this, it was hard to determine what the answer was. It would have helped if it was a little clearer
I hope this helps you
