Answer: 20
Explanation: Alright, so basically you’re going to want to use PEMDAS (Parenthesis, Exponents, Multiplication/ Division, Addition/ Subtraction)
* just means multiply.. sooo the problem looks like this:
6x(12-7.5)-7
We’ll start at the parentheses :)
So (12-7.5) = 4.5
Now our problem looks like: 6x(4.5)-7
Following PEMDAS, the next thing to come up is multiplication! So we’re going to multiply 6 by 4.5 ...
6x4.5=27
After this our problem looks like: 27-7
So now it’s just simple math...
27-7= 20
The function:
f ( x ) = x * 0.965^t
where x is the initial amount and t is the number of the years
80 = x * 0.965^3
80 = x * 0.89632
x = 80 : 0.89632 ≈ 89
Answer:
The initial amount of animals was 89.
Hope this helps!
Have a nice day :)
