given information:

dan used 942 units of electricity from july to october.

the meter reading in july was 32347 units.

asked:

a)work out the meter reading in october.

b)each unit costs 14p. how much do 942 units cost?

> suppose that the total no. of units used will be divided equally to the months of july, august, september, and october. so, we have 942 units divided by 4 months is 235.5 units. each month, dan used 235.5 units.

now, let us work for each reading. since it is said that july has 32347 units, we will add 235.5 units so we can have the meter reading for august. same goes with the rest of the months. 235.5 units is added on each result of the previous month.

say,

month previous reading present reading units used

july 32111.5 32347 235.5

august 32347 32582.5 235.5

september 32582.5 32818 235.5

october 32818 33053.5 235.5

a) therefore, october has a meter reading of 33053.5 units. we should indicate the previous reading of the month so that we can calculate how much units of electricity is used up.
b) multiply 942 units with 14 so we can calculate the cost of 942 units.

942 x 14 is 13, 188
