Days when the fish gets to 30
The function is exponential and as such it follows;

Where x represents the number of days and y the number of fishes
Because the fishes decreases;

So, we have:

Express as decimal


In 



So, we have:

Divide both sides by 150

Take log of both sides

Apply law of logarithm

Make x the subject




<em>Hence, it takes approximately 19 days</em>

Answer:100 chocolates
Step-by-step explanation:
20 chocolate in each box so 20 time 5 is 100 so 20 time 11 is 220
To more easily graph this, convert it to slope-intercept form (y = mx + b, where m is the slope and b is the y-intercept):
x - y = 1
-y = -x + 1
y = x - 1
The slope is 1 and the y-intercept is -1. To graph this, plot the point (0, -1) and count 1 unit down and 1 unit to the right. Do this once more, connect the points, and you have your line.
Hope this helps.
