0002343 is the current reading on a meter. If electricity costs $0.50 per kwh, what would be the new meter reading after paying $400 on a bill

Question

Math Consumer Arithmetic

Answer 1

Assuming that the meter reading is in kWh,

If electricity costs $0.50 per kWh,

Thus in bill of $400, the electricity units consumed will be $400/$0.50 = 800 units,

The new meter reading would be 0002343 + 800 = 0003143
