2- 3 balls of wool 3-I think 18 dollars 4- 287 miles 5a- people served:24 ,liters of soda:4 ,Pints of sherbet:2 ,Cups of ice:6 5b- for 12 ppl you would need 2 liters of soda,1 pint of sherbet,and 3 cups of ice. For 36 ppl you would need 6 liters of soda,3 pints of sherbet, and 9 cups of ice. 5c-for 18 ppl you would need about 3.00000001 liters of soda, 1.5 pints of sherbet, and 4.50000001 cups of ice. To figure this out you need to do 24 divided by 18 (24/18) and you get 1.33333333. So for liter of soda you do 4/1.33333333 and get 3.00000001 and you divide every number in the original problem by 1.33333333
To find this answer, just divide 360 by 5 to find out how many times his heart beats in one minute instead of 5. Doing this will give you a final answer of 72 bpm.
