5. a)Write an expression, in terms of K, for the number
of dollars Cindy has.
• B = K – 6
• C = 2B = 2 (K – 6) = 2K – 12
b) Cindy has $4 less than Adi. Work out the value of
K.
2K – 12 = K – 4
2K – K = -4 + 12
K = 8

11. Area of path = (8 + 1 + 1)(6 + 1 + 1) – (8 x 6)
m2
= (10 x 8) – (8 x 6)
= 80 – 48
= 32
Stones he needs
= 32 x 50 kg = 1600 kg = 1.6 tonnes
The number of stones he needs to buy
= 1.6 : 0.75
= 2.13333
So, he need to buy 3 bags of stones
