(a) Explanation Consider y is the sale of the digital track in millions and x be the years after 2004. It is given that 142 million tracks were sold in 2004. Therefore, the base amount will be 142 million. And, the rate of increase in the amount is 219 million digital track per year... (b) To determine To calculate: The year when the digital track sale and album sales are equal and the number of sales of each product in that year if the function that models the number of albums sold is 95 x + y = 770 where x is the year after 2004 and y is the number of albums sold.Refer to the bar graph provided in the question.
