Answer:
8% increase
Step-by-step explanation:
In this question, we are asked to calculate the percentage increase that a certain increment will give over a period of 10 years.
Let the increment be x
Mathematically from the question, we can obtain that ;
(1+x)^10 = (1+1.2)
(1+x)^10 = 2.2
1+ x = 2.2^1/10
1+x = 1.082
x = 1.082 - 1
x = 0.082
This means that x = 8.2% which is approximately 8%
Simply just divide 5 and 3/5:
5/(3/5)=25/3
Therefore, 5 cups of birdseeds will last 25/3 days.
I think this is how it’s done.
