Answer:
$4.8
Step-by-step explanation:
$24×20/100=$4.8
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

Answer:
$45.43
Step-by-step explanation:
20 × 0.18 = 3.60
18.50 × 0.18 = 3.33
3.60 + 3.33 = 6.93
The total in tips is 6.93
20 + 18.50 = 38.50
The total meal cost is 38.50
38.50 + 6.93 = 45.43
The total of everything is 45.43
It’s B because they both equal each other I would explain more but I’m in class but the answer is definitely B
