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

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
