Lori buys goldfish for her tank her research shows that they will reproduce at a rate of 32,percent each month. Which statement discusses a key feature of the graph of this situation

The points on the graph will have a common ratio of 32
The graph will begin with the point (1,5) because Lori starts with 5 fish
The graph will have a constant rate of change
The points on the graph will have a common ratio of 1.32

1 answer

The most accurate statement regarding the key feature of the graph for Lori's goldfish situation is:

The points on the graph will have a common ratio of 1.32.

This is because the goldfish are reproducing at a rate of 32% each month, which means that each month, the number of fish will increase by a factor of \(1 + 0.32 = 1.32\). Therefore, if you start with 5 fish, the number of fish can be modeled by multiplying by 1.32 each month.

To clarify the other options:

  • The points on the graph will not have a common ratio of 32, as the reproduction rate needs to be expressed as a growth factor rather than a percentage.
  • The statement about starting with (1,5) is incorrect; it should be (0,5) if representing the starting month as zero.
  • The graph will not have a constant rate of change; instead, it will have an exponential growth pattern due to the percentage increase in the population each month.
