Pls help An electronics store keeps track of the number of computers sold. Last month, 30% of the computers were notebooks. If the store sold 390 notebooks last month, what was the total number of computers sold in the same month?

1,300 computers
1,560 computers
975 computers
1,114 computers

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
