The north shore news charges $19.50 for a two-line classified ad. Each additional line costs $8.50. For an extra$40 a seller can include a ohoto in the ad. How much would a four-line ad with a photo cost?
The first two lines will cost $19.50, according to the problem. Since we need four lines, we need additional two lines, which cost 2*$8.50=$17. The four lines cost 17+19.5=$36.5. One photo costs $40, so in total they cost 36.5+40=76.5 dollars.
