Hawk’s dog walker charges $25 per week for 4 walks. Each additional walk is $10, and grooming can be added for an additional $35. Or Hawk can pay a flat rate of $250/month, which includes daily walks and 1 grooming. Hawk would also like to give a tip of either $5/week or 20% for the month. If Hawk pays the weekly rate for a total of 4 weeks with an additional walk every week plus 1 grooming, how much will each option cost with gratuity? What will the weekly rate plus the tip equal? What will the monthly rate plus the tip equal?

Hawk’s weekly rate for 4 walks is $25/week * 4 weeks = $<<25*4=100>>100.

To add a fifth walk each week for an additional 4 weeks, it will cost $10/walk * 4 weeks = $<<10*4=40>>40.
Adding grooming for 1 session will cost an additional $35.
So the total cost for 4 weeks with 5 walks and grooming is $100 + $40 + $35 = $<<100+40+35=175>>175.
If Hawk pays a tip of $5/week for 4 weeks, the total gratuity will be $5/week * 4 weeks = $<<5*4=20>>20.
So the total cost with gratuity for 4 weeks with the weekly rate will be $175 + $20 = $<<175+20=195>>195.

The monthly rate is $250 which includes 4 weeks of daily walks and 1 grooming session.
If Hawk chooses a 20% tip for the month, the tip amount will be $250 * 20% = $50.
So the total cost with gratuity for the monthly rate will be $250 + $50 = $<<250+50=300>>300.

The weekly rate plus the tip will be $175 + $20 = $<<175+20=195>>195.

The monthly rate plus the tip will be $250 + $50 = $<<250+50=300>>300. Answer: \boxed{300}.
