Answer:

Mr Johnson works out the cost of the gas he used last year is 573.32 rs.  At the start of the year, the gas meter reading was 8569 units. At the end of the year, the gas meter reading was 9872 units. Each unit of gas he used cost 44p.

Step-by-step explanation:

At the start of the year, the gas meter reading = 8569 units

At the end of the year, the gas meter reading = 9872 units.

So, gased used in last year = 9872 - 8569= 1303 units

If the cost of each unit of gas = 44 paise

Then cost of 1303 unit = 1303 × 44 = 57,332 paise

or = 573.32 rs.

So, Mr Johnson works out the cost of the gas he used last year is   573.32 rs.
