Question

11. Chris buys six guppies. Every month his guppy population doubles. [4]

a) How many guppies will there be after 1 month? 2 months? 3 months?
b) Create a formula that would express the statement above. In your formula let n
equal the number of months, and G equal the total population of guppies.
c) How many guppies will there be after 6.5 months?
d) Can the fish population continue to grow at this rate? Explain

Answer 1

G = 6(2)^n

Explanation:

a) At 1 month he will have 12 guppies, at 2 months he will have 24 guppies and at 3 months he will have 48 guppies.

b) G = 6(2)^n

This is following the exponential formula.

c) G = 6(2)^6.5 = 543 guppies

d) At this rate, there will be no room for the guppies to continue growing.
