MJ wants to reduce the price of the ad. So, instead of a 6-line ad, she reduced it to a 4-line ad. The following piecewise function gives the price of an x-line posting. The price of the ad is $35 if the ad is 4 lines or less. The price of the ad is $ 35 + 8 ( x - 4 ) if the ad is more than 4 lines. How many lines is MJ placing?
Which formula should you use based on the number of lines in the ad?
