Step-by-step explanation:
In order to get the mean cost that she wants from the gift, we would need to get the numbers that we already had, and have another set of row with the amount of gifts she needs with the mean she wants.
Here is how it should look like:
$25 $14 $33 $19 x
$25 $25 $25 $25 $25
We are trying to find the number for "x"
Therefore, we would need to use the process of adding, then subtracting after.
Lets add:
What we would do now is subtract the numbers in order to get the price that Tonya wants from her gift, if she buys another gift.
Tonya should spend $34 on her last gift.
$34 should be your FINAL answer

Answer:
The exact solution is
And the approximation to three decimal places is:
x = 0.363
Step-by-step explanation:
Here we have the equation:
Now we can remember a property of the natural logarithm function:
Ln(a^n) = n*Ln(a)
Now we can apply the Ln( ) function to both sides of that equation to get:
Then we get:
Solving that for x we get:
So the exact solution is:
And the approximation to three decimal places is:
x = 0.363
