**urgent** a computer company sold 12 more computers the second week than the first week, and they sold twice as many computers the third week as the second week. if the total number of computers sold was 220, how many computers did they sell each week?

1st week they sold 98 computers
2nd week they sold 110 computers
3rd week they sold 220 computers

there you go :)

So I set up the equation up as X= computers, x+x+12+2(x+12)=220. 
then you would find the value of x which should be 46. 
so the 1st week he sold 46 computers, for the second week he sold 58 computers, then 116 the third week.

You can plug them into the x spots, for example, the second week he sold 12 more than he did the last week so it would be x+12= number sold so 58.

To check if you got it correct, plug it back into the equation to see if it equals 220 which it does.
