We’ll first find how much she has left as her savings
$490-$396.90= $93.70
Now we’ll go for cross multiplication
100% $490
? $93.70
? = 100 x 93.7/490
? = 19.1 %
So the answer is 19.1% which rounded to the nearest whole number is 19%. The answer is the first option.

Yes that statement is true.
The average rate of change of function
from x = 3 to x = 4 is 4 times that from x = 1 to x = 2.
The correct option is (A).
What is the average rate of change of a function?
The average rate at which one quantity changes in relation to another's change is referred to as the average rate of change function.
Using function notation, we can define the Average Rate of Change of a function f from a to b as:

The given function is
,
Now calculating the average rate of change of function from x = 1 to x = 2.

Now, calculate the average rate of change of function from x = 3 to x = 4.

The jump from m = 10 to m = 40 is "times 4".
So option (A) is correct.
Hence, The average rate of change of function
from x = 3 to x = 4 is 4 times that from x = 1 to x = 2.

Answer:
The two numbers are 5 and 1. Their product is 5
Step-by-step explanation:
x + y = 6 (*)
x - y = 4 (**)
Let (*) + (**)
--> (x+y) + (x-y) = 6 + 4
<=> 2x = 10 <=> x = 5
Substitute x= 5
(*) <=> 5 + y = 6
<=> y=1
Answer: (x,y) = (5,1)
Their product: x.y = 5x1 = 5
