Apples cost £2.40 per kilogram. How much do 3.5 kilograms cost?
Answer and explanation
Correct answer: C. £8.40
- Step 1: 3.5 x 2.40 = 3 x 2.40 + 0.5 x 2.40.
- Step 2: That is 7.20 + 1.20 = 8.40.

£8.40.
Why not the others: £7.20 is the cost of only 3 kg, £8.04 misplaces a digit and £9.60 is the cost of 4 kg.
