Final answer:
Jason's dog ate 3/20 of the 160 meatballs, which equals 24 meatballs. After subtracting the 24 meatballs eaten by the dog from the total, Jason has 136 meatballs left.
Step-by-step explanation:
To find out how many meatballs Jason has left after his dog ate 3/20 of them, we first need to calculate the amount eaten by his dog. Jason cooked a total of 160 meatballs. To calculate 3/20 of 160, we multiply 160 by 3/20:
160 x 3/20 = 24
So, the dog ate 24 meatballs. To find out how many are left, we subtract the amount eaten by the dog from the total number cooked:
160 - 24 = 136
Jason therefore has 136 meatballs left.
