An initial number of bacteria presented in a culture is 1,000. This number triples every 30 minutes. Write a function expressing
Svetlanka [38]
Tripiling time is
A=P(3)^ \frac{t}{r}
t=time elapsed
r=tripling time
P=initial amount


so


A=1000(3)^ \frac{t}{30}
when time is measured in minutes
if measured in hours then

I don’t get it. Please help thanks
Likurg_2 [28]

Answer:

$2,410.69

Step-by-step explanation:

$1,950 x 1.15 = $2,242.50 after 15% markup

$2,242.50 x 1.075 = $2,410.68 after the 7.5% sales tax.


or you can do:


$1,950 x 0.15 = $292.5 markup

$1,950 + $292.5 = $2,242.50

$2,242.50 x 0.075 = $168.19 for sales tax

$2,242.50 + $168.19 = $2,410.69 total
