Answer:
it so easy that correct
Step-by-step explanation:
$500.00×$8.5
Every 56 seconds, the radioactive substance is divided in half.
224 / 56 = 4
We need to cut the substance in half 4 times.
896 / 2 = 448
448 / 2 = 224
224 / 2 = 112
112 / 2 = 56
After 224 seconds, there will be 56 grams of the radioactive substance left over
It will be negative because he has 422 but purchased 484 which is more than he has . so he is a negativge nuber because owns money
