a)
he charges a fixed cost of $12, meaning a one-time charge of 12 bucks, plus 1.50 for each window.
1 window................ 12 + 1.5(1)
2 windows............. 12 + 1.5(2)
3 windows............. 12 + 1.5(3)
4 windows............. 12 + 1.5(4)
x windows............. 12 + 1.5(x)

b)

If the perimeter is 26 and the length of one side of the rectangle is 5cm longer than its breadth,
26 - 5 - 5 = 16
16 / 4 = 4 ( rectangle has 4 sides. )
the breadth is 4cm.
so the length must be 4+5=9cm.
There are a total of 16 movies to choose from and 6 of them are comedy. This means that you have a 38% of choosing comedy. But the chances of you not choosing comedy is 62%. And since your friend is also choosing, the chance of neither of you not choosing is cut in half.
So, the final answer of neither of you choosing comedy is 31%
