Question

Jane moved into a flat with two other students. the rent was £540 per month altogether and the council tax worked at £216 each per year.

gas and electricity charges are as follows:

gas
cost per unit = 27.2 pence
standing charge (per quarter) = £12.40

electricity
cost per unit = 7.1 pence
standing charge (per quarter) = £9.10

their meter readings were :

gas
oct 1 = 9586
dec 31 = 9873

electricity
oct 1 = 3187
dec 31 = 3542

the telephone bill for the first quarter showed that 906 units had been used at 5 pence per unit (including VAT)

assuming that all bills are shared equally, how much did jane's first 3 months in the flat cost her?

Answer 1

9873 - 9586 = 287 units used cost is 287 * 27.2 = 7806.4 p= 78.06 + standing charge of 12.40

total gas 80.46 Jayne's share 26.16 (because they have to pay part of a penny, so round up)
electricity
3542 - 3187 = 355 units used cost 355 * 7.1 2520.5 p = 25.21 + standing charge of 9.10

total electricity 34.31 Jayne's share 11.44 (because they have to pay part of a penny, so round up)
Rent * 3 months = 540 * 3 = 1620 Jayne's share 1620 / 3 = 540

total cost 3 months for Jayne
540 + 11.44 + 26.16+ 54 = 631 pounds 60 pence
