Dan used 942 units of electricty from july to october. the meter reading in july was 32347 units. a)work out the meter reading in october. b)each unit costs 14p. how much do 942 units cost?
working out !

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

to rewrite a literal equation you may need to divide by a number, or by a variable.
