You can spend 21 and still have 62 for taxes thank me later shorty (I literally don’t know if this is right) you might wanna ask your teacher for help all I didn’t was subtract 47 and 4.6%
For 12 people it would be 2 liters of soda, 1 pint of sherbet, &3 cups of ice. you wanna make half as much as his recipe says so just divide everything by 2. then you can multiply what the half recipe calls for to serve 36 people by three. so it would be 6 liters of soda, 3 pints of sherbet and 9 cups of ice. I hope that made sense to you, it was kind of hard to out the explanation into words
