equation for sarah is y1 = 10x, where x = the number of hours she works and y equal the amount of money she makes in a season.

equation for ads are us is y2 = 120 which is the amount ads are us charges for the season.

the intersection of these two equtions is when y1 = y2 which is the same as when 10x = 120.

this occurs when x = 120 / 10 = 12.

the point of intersection means that the most sarah can make for the season working for ads are us is 120 and the maximum number of hours she needs to work for this money is 12 hours.
