         C={1,2,3,6}
         U= {1,2,3,4,5,6,7,8,9,10}

A' = {1,3,5,7,9}
B' = {1,2,4,5,7,8,10}

(1b)
Cost of each premiere ticket = $18.50
At bulk purchase, cost of each = $80.00/50 = $16.00

Amount saved = $18.50 - $16.00
=$2.50

(5a)
Total income = 32+m+25+40+28+45
=170+m
PR(²)=m/170+m = 0.15/1
M=0.15(170+m)
M=25.5+0.15m
0.85m/0.85=25.5/0.85
M=30

(5b)
Total outcome = 170 + 30 = 200

(5c)
PR(even numbers) = 30+40+50/200
=115/200 = 23/40

8a) Cost price = Ghd 150

Let the number of plates be X profit per one = 1 GHd

Total profit = 6 GHd

Remaining plates = x - 4

Total profit = (x - 4) 1Ghd

6 = x - 4

X = 6 + 4

X = 10


The number of plates is 10.

11b)  8y = - 4x + 24

Y = - 4/8 x + 24/8

Y = - 1/2 x + 3

Gradient = m = - 1/2

:. Y- y1 = m(x-x)

Y- 12 = 1/2 (x + 8)

2(y-12) = 1 (x+8)

2y - 24 = -x-8

X + 2y - 24 + 8 = 0


X + 2y - 24 + 8 = 0

X + 2y - 16 = 0

Is the line above
