A1)how many units of electricity was used if the previous meter reading was 45678 and the new reading was 50001 a2) the next trading was 50451 how many units were used this time?

b) what will be the cost of the electricity in each case assuming it costs 15p per unit?

c) how do you think the reading will change for: (i) the winter (ii) the summer? why do you think this?

if someone could awnser one of these you’ll be an absolute life saver
