###Human: Andy gets a cavity for every 4 candy canes he eats. He gets 2 candy canes from his parents and 3 candy canes each from 4 teachers. Then he uses his allowance to buy 1/7 as many candy canes as he was given. How many cavities does he get from eating all his candy canes?, ### Assistant: First find how many candy canes Andy gets from his teachers: 3 canes/teacher * 4 teachers = 12 canes
Then add the number of candy canes he gets from his parents: 12 canes + 2 canes = 14 canes
Then divide that number by 7 to find the number of canes he buys: 14 canes / 7 = 2 canes
Then add the number of candy canes he gets from each source to find the total number: 2 canes + 14 canes = 16 canes
Then divide the total number of candy canes by the number of candy canes it takes to get one cavity to find the number of cavities Andy gets: 16 canes / 4 canes/cavity = 4 cavities 
 So the answer is :  16
