Lesson 2 semester B exam algebra 1B unit 7
Elodia [21]
<h2>Answer:</h2>

720 pounds

<h2>Step-by-step explanation:</h2>

Initially, we have that the amount of algae in the pond is 90pounds. Every four hours the amount of algae doubles. If we called t the time and W the amount of algae, we have that:

At \ t=0 \ hours, \ w=90 \ pounds \\ \\ At \ t=4 \ hours, \ w=2(90)=180 \ pounds \\ \\ At \ t=8 \ hours, \ w=2(180)=360\ pounds \\ \\ At \ t=12 \ hours, \ w=2(360)=720 \ pounds

Finally, <em>after 12 hours the amount of algae in the pond is 720 pounds</em>
