What examiners said
There were two stages to this calculation. The first stage was finding out how much energy was used, using the equation E = P × t. This gives the amount of energy in kWh, 13.2. The second stage is to find the total energy cost by multiplying the amount of energy, 13.2 by 0.25 to give $3.3. Overall, candidates found this question demanding. Some candidates could have gained partial credit if they h...
