Company B charges a flat fee of $10 plus $2 for each day that you rent your skis. (a) Write an equation which expresses the total rental cost at Company A as a function of the number of days you rent your skis. Write another equation which expresses the total rental cost at Company B as a function of the number of days you rent your skis. (b) When is it cheaper to rent from Company A?
