Answer:
<u>About 8.5 mins</u>
Step-by-step explanation:
This is a compound decay problem, which goes by the formula:
Where
F is the future amount (we want it to be 380)
P is the present amount (980 now)
r is the rate of decay per minute (10.5% = 10.5/100 = 0.105)
t is the time it takes (what we want to find)
Substituting, we get our answer to be:
SO, it is going to take about 8.54 mins, rounded to nearest tenth (1 decimal), we have:
<u>About 8.5 mins</u>
