The new reading for James' electricity bill is 7580, and the old reading is 7510, the price per unit is 13p, how much does James have to pay for his electricity?

This question is tricky/unfair because you need to understand how meters work. The old reading was the last time the electricity bill was paid for, so the first thing you need to do is 7580-7510= 70. So that's how many units James used.70 x 13 = 910 p **student would need to work out multiplication
910/100 = 9 pounds and 10 pence
