4 because there are 4 kinds of marbles
Answer:
Step-by-step explanation:
Given:
The functions given are:
To find:
is equal to the addition of both the functions. So, we need to add the values of both the functions and then simplify to arrive the final answer.
Therefore, is given as:
Plug in the values of and simplify. This gives,
Combining like terms using commutative property of addition, we get
Therefore, the addition of the two functions is simplified to:
First determine how much it increased by. 36+X=64
X=28
It increased by 28
Now determine what percentage 28 is of 36
36(Y)=28
Y=.77777778
28 is a 77.78% (.7778) increase from 36
After you round, your answer is 78%
