You can put this solution on YOUR website!
A person sold 120 items in x+2 days.
If he sold at the same rate for a seven day week, how many items did he sell during the seven days?
:
Find out how many sold in 1 day
120%2F%28%28x%2B2%29%29 = no. of items in 1 day
then in 7 days:
7(120%2F%28%28x%2B2%29%29)
simplify to
840%2F%28%28x%2B2%29%29 = no. of items sold in 7 days

Did this make sense to you now?

Response to student's question
Actually you can't solve this, because there is no way to know just what x is.
840%2F%28%28x%2B2%29%29 in seven days; is as far as you can go with it
This is not an equation, just an expression.
(I probably should not have used the = sign here)
