    Answer:

    1,300 computers

    Step-by-step explanation:

    As, they are saying they sold 30% of the computers last month

    And that 30% was 390

    So, x = the total number of computers

    30% of x = 390

    30% = 30/100 and “of” represents multiplication

    So 30/100 X x = 390

    We will transpose everything

    30x = 39000

    x = 39000 ÷ 30 = 1,300

    So 1,300 computers were sold
