Final answer:
The number of guppies over time can be modeled using a function. To find out how many months it takes to reach 100 guppies, we need to set the function equal to 100 and solve for t.
Step-by-step explanation:
The number of guppies over time can be modeled using a function. Let's say the function is represented by N(t) where t represents the number of months since the start and N represents the number of guppies.
To find out how many months it takes to reach 100 guppies, we need to set N(t) = 100 and solve for t. This will give us the time it takes for the number of guppies to reach 100.
For example, if the function is N(t) = 2t + 50, we can set 2t + 50 = 100 and solve for t.
