Answer:

900

Step-by-step explanation:

If 40% per month = 300. Multiply 300 by 3.

Answer:

823 pounds of trash. ( approx )

Step-by-step explanation:

Since, the exponential growth function is,

[tex]A=P(1+r)^t[/tex]

Where,

P = initial value,

r = growth rate per period,

t = number of periods,

Here, P = 300 pounds, r = 40% = 0.4, t = 3 months,

Thus, the quantity of trash after 3 months,

[tex]A=300(1+0.4)^3=300(1.4)^3 = 823.2\approx 823\text{ pounds}[/tex]
