If Jake has 30 chocolates, and he ate 20, what does he have now?
Idk why you asked but he has 10 chocolates and something that affected his stomach and his other belongings+his children or parents
30 chocolates−20 chocolates=10 chocolates.
30 - 20 = 10 chocolates.
Hence the final answer is 10 chocolates.
