Answer:
10s+40m+61l=net profit
Step-by-step explanation:
subtract the value you pay from the value you charge
Let's assume
It started in 2000
so, t=0 in 2000

we can use formula

we can plug value

In 2005, the same survey was made and the total amount of gamma ray bursts was 7.3 million
so, at t=2005-2000=5
P(t)=7.3 million
we can plug value and then we can solve for r


now, we can plug back

now, we have
P(t)=1 billion =1000 million
so, we can set it and then we can solve for t


approximately

Year is 2000+192
year is 2192................Answer
A can be converted since it is a repeating decimal
Rounded to the nearest cent, the answer is 1.19
