1) A recycling company breaks down and delivers recycled plastics. The
recycled plastic is packaged in boxes that are cubes with edge length
30cm. The cost of the plastic is \$12/m3 , and delivery costs \$15 per 30km. One
customer orders 200 boxes of plastic and he lives 120 km from the supplier.
This expression represents the cost, in dollars:
15 x 120
+ 303 ÷ 156 x 12 x 200
30
How much doe the customer pay? (3 marks)
2) Copy each statement. Insert brackets to make each statement true.
(3 marks)
a. 20 ÷ 2 + 2 x 22 + 6 = 26
b. 20 ÷ 2 + 2 x 22 + 6 = 8
c. 20 ÷ 2 + 2 x 22 + 6 = 120
