5 + 8s = 15 + 3s
8s - 3s = 15 - 5
5s = 10
s = 10/5
s = 2 <=== they will charge the same at 2 sq ft
The microphone was $126.
You would multiply $38 by 6 which equals $228.
Then do $354-$228 which equals $126.
Divide the pentagon into a triangle and rectangle.
Rectangle: 12in*6in=72in^2
Triangle: (12in*5in)/2=30in^2
72in^2+30in^2=102in^2
First you divide 24 by 3 then your answer should be 8 then you do 8x2 so the answer is 16
