First we need to know how many months is 2 years. To answer that we multiply the number of months in a year by 2 and get 48 months.
Every 3 months the population of turtles doubles, but to get how many times the population doubles, you need to divide 48 months by 3 to get 16.
So population of 400 will get <u>doubled</u> 16 times in the following <u>two</u> years.
We construct the following equation where
is the final population,

Hope this helps. :)
5x$12= 60$ so 60$per week 60$x12 = $720 for the Medium dogs.
8x14$= 112$ per week, she walked them 12 weeks. 112x12= $1344 for the large dogs.
Now take the two prices $720+$1344= $2,064
She earned a total of $2,064 from walking the dogs.
Hope this helped.
