(2a)
Let cutlass = x and hoe = y
3x+2y = 85
2x+3y = 90

6x+4y = 170
6x+9y = 270

-5y = -100
y = -100/-5 = 20
:. 2x+3(20) = 90
2x = 90 -60 = 30
x = 30/2 = 15
Cutlass cost GHc15 and hoe cost GHc20

(2b)
y = k(x-4)(x-1) = 24
y = k(x²-5x+4) = 24
x =0
24 = k(4)
k = 24/4 = 6
====================================

(5a)
12/25
Pr(even)=12/25

(5b)
Pr(prime) =9/25

(5c)
Pr(even or prime )
=12/25+9/25
=21/25

(5d)
Pr(both prime and even)
=9/25*12/25
=108/625
