Answer: I really do not know how to fix your problem. Maybe restart your phone?!
area of painting = 13 * 17 = 221 square inches
221 * 0.30 = 66.30
the price would be $66.30
After 6 hours the radioactive compound with mass 470 grams becomes 391.49 grams and the equation will be C is equal to 470(1-0.03)^6.
<h3>What is exponential decay?</h3>
During exponential decay, a quantity falls slowly at first before rapidly decreasing. The exponential decay formula is used to calculate population decline and can also be used to calculate half-life.
We know the decay can be as:

We have:
a = 470 grams
r = 3% = 0.03
t = 6 hours

C = 391.49 grams
Thus, after 6 hours the radioactive compound with mass 470 grams becomes 391.49 grams and the equation will be C is equal to 470(1-0.03)^6.
