A branch circuit for a copy machine has $124$ volts available at the circuit breaker. Because the copier draws $15\mathrm{.}4$ amps, there is a total of $13\mathrm{.}2$ volts dropped in the branch circuit conductors. With the copier operating, the voltage that would be measured at the receptacle where the copy machine is connected would be $\_\_\_$ volts.Select one:a$\mathrm{.}15\mathrm{.}4$b$\mathrm{.}124$c$\mathrm{.}106\mathrm{.}8$d$\mathrm{.}120$e$\mathrm{.}110\mathrm{.}8$
