Let us say that:

x = is the number of ads that Nadia sold every week

P = payment or amount that she receives every week

 

So the equations we can formulate for choice A and B are:

choice A: P = 110 x

choice B: P = 150 + 85 x

 

The amount that she receives for A must be greater than she receives for choice B, so:

110 x > 150 + 85 x                       (inequality equation)

 

Calculate for x:

110 x – 85 x > 150

25 x > 150

x > 6

 

Therefore Nadia must sell more than 6 ads every week so that Choice A would be the better choice.
