Answer:
1350 ounces
Step-by-step explanation:
If the bacteria doubles by every 3 hours since our initial amount is 135, it will be;
15hours/3hours = 5hrs
then multiply the bacteria by to find the single amount after the period of time
5hrs × 135 ounces = 675 ounces
then multiply this by two to find the doubled amount; 675 × 2= 1350 ounces
Answer:
4320 ounces.
Step-by-step explanation:
The bacteria doubles every 3 hours. Therefore in 15 hours it will double up 5 times.
at t=0 => [tex]2^{0}[/tex]x135 = 135
at t=3 => [tex]2^{1}[/tex]x135 = 270
at t=6 => [tex]2^{2}[/tex]x135 = 540
at t=9 => [tex]2^{3}[/tex]x135 = 1080
at t=12 => [tex]2^{4}[/tex]x135 = 2160
at t=15 => [tex]2^{5}[/tex]x135 = 4320
