You need a total of 50 pounds of two types of ground beef costing $1.25 and $1.60 per pound, respectively. A model for the total cost y of the two types of beef is y = 1.25x + 1.60 (50 - x) Where x is the number of pounds of the less expensive ground beef. a) Find the inverse function of the cost function. What does each variable represent in the inverse function? b) Use the context of the problem to determine the domain of the inverse function.

a mix with a total cost of x=$73.

Of course, 30 pounds (50 pounds - 20 pounds = 30 pounds) of that mix will be the more expensive ground beef.
