Answer provided by our tutors

let


x = the number of computers sold

y = the number of external hard drives sold


a computer store sold a total of 36 computers and external hard drives


x + y = 36


the revenue from these sales was $27,710


1180*x + 125*y = 27710


by solving the system of equations


x + y = 36

1180*x + 125*y = 27710


we find


x = 22 computers


y = 14 hard drives


the store sold 22 computers and 14 hard drives.
