Question
The weekly profit model has roots at x = -52.789, x 47.555, and a decimal places. 202.944, rounded to 3 The marginal weekly profit model has roots at x = -8.488 and x = 140.295, rounded to 3 decimal places. Yaster Outfitters • makes a profit on extreme-cold sleeping bags when the weekly production level a satisfies A < x < B; • loses money when 0 < x < A or x > B. In other words, Yaster starts making a profit when production exceeds A sleeping bags per week, and starts losing money when production exceeds B sleeping bags per week. Round A and B to 3 decimal places. What is A? Round to 3 decimal places. sleeping bags What is B? Round to 3 decimal places. sleeping bags Page 1 of 1 O words * Accessibility.
