Hey there, Kellygarcia40!
The equation should be
Future Amount = 20 [tex] (1 + 1)^{x} [/tex]
x being the number, or set, of every 30 days
210 days can be turned into 7 sets of 30 because 210 divided by 30 is equals to 7
In the equation, we can replace x for 7, and it will look something like this
Future Amount = 20 [tex](1 + 1) ^{7} [/tex]
Future Amount = 20 [tex] (2)^{7} [/tex]
Future Amount = 20 (128)
Future Amount = 2,560
There will be 2560 rabbits after 210 days.
Thank you for using Brainly.
See you soon!
