maths

i’ve got a maths problem i’m really stuck with

it is -

grace receives a gas hill. the details are as follows.

present meter reading - 4300
previous metre reading - 2342
charge per unit - 5p per unit
service charge - £10.25
VAT - 5%

what is the total cost of gas for this bill?

does anyone know how to work this out
any help would be appreciated
thank you
It's been a while since I've done one of these questions but I'm pretty confident I can explain it.

1. Work out how many electricity units have been used in the month through subtraction, 4300-2342=1958 units
2. Multiply the number of units by the cost, (£0.05 as I've converted the 5p to £) 1958x0.05=£97.90
3. Add the cost of service (how much you have to pay to be part of the grid, doesn't matter how much electricity you have used) 97.90+10.25=£108.15
4. Multiply to include VAT as it's a percentage (x1.05 is the same as increase by 5%) 108.15x1.05=113.5575
5. Round to get the answer in £, 113.5575 to £113.56

So assuming I've done everything right the answer should be £113.56
I advise running through all the sums I've done again, I did it quite hurriedly.

Happy to help

Just happy to help, the method is simple once you know it but until then these questions seem very confusing.
