Elec  = R125 × 12,2 mil = R1 525mil MA
Water =R98 × 10,6 mil = R1 038,8 mil ü MA Monthly total in million
Total spent on electricity and tap water in millions:
= R2 563,8 × 12 = R30 765,6     CA

OR
Elec = R125 × 12,2 mil = R1 525 mil
Total for the year 
= R1 525 million × 12
= R18 300 million   MA 

Water = R98 × 10,6 mil = R1 038,8 mil
Total for the year
= R1 038,8 million × 12
= R12 465,6 million  MA
Total spent on electricity and tap water in millions:
M
= R18 300 + R12 465,6 = R30 765,6    CA

OR
Annual cost for electricity 
= R125 × 12 = R1 500
Total electricity
= R1 500 × 12,2 million  = R18 300 million
MA Annual cost for tap water
= R98 × 12 = R1 176
Total :water= R1 176 × 10,6 million
= R12 465,6 million   MA 

Total spent on electricity and tap water
