Hello! I need help with this question please. thank you very much

D Question 20 8 pts Use the following information for questions 20-23: There are two ways of mowing grass, using a machine and manually. The marginal costs of mowing grass using the different methods are MC, = 0.40, and MC = 22 + Q, where Q, represents the number of squared feet mowed using each method (method 1 is by machine and method 2 is manually)- Assume you want to mow 1000 squared feet at the lowest possible total cost. How many squared feel should you mow using method 1 (Le. the machine)? Enter only the number, without symbols or words. D Question 21 8 pts How much should you mow using method 2? Enter only the number, without symbols or words. D Question 22 3.5 pts At the point of cost minimization, MC1 is equal to: (Enter only the number, without symbols or words.) D Question 23 3.5 pts At the point of cost minimization, MC% is equal to: (Enter only the number, without symbols or words.)
