This is the "problem 5" that the question in top is talking about

Problem 5 Using Standard Form as a Model Online Shopping A media download store sells songs for $1 each and movies for $12 each. You have $60 to spend. Write and graph an equation that describes the items you can purchase. What are three combinations of numbers of songs and movies you can purchase? cost of Relate number cost of number a song times of songs plus a movie times of equals $60 movies Define Let X the number of songs purchased. Let y = the number of movies purchased. Write X + 12 V 60 An equation for this situation is x + 12y = 60. Find the intercepts. 0 songs 5 movies Downloads x + 12y = 60 x + 12y = 60 24 songs x + 12(0) = 60 0 + 12y = 60 3 movies x = 60 y = 5 Number of Movies 60 songs O - NWAUT Use the intercepts to draw the graph. Only points in the 0 movies first quadrant make sense. The intercepts give you two combinations of songs and '0 12 24 36 48 60 movies. Use the graph to identify a third combination. Number of Songs Each of the red points is a possible solution. Check for Reasonableness You cannot buy a fraction of a song or movie. The graph is a line, but only points with integer coordinates are solutions
