Answer:
$295.01
Step-by-step explanation:
Using the compounding continuously formula, we are looking for A. We have that P = 190; r = .11 (always use the decimal form of the rate!); and t = 4. Filling in we have:

Simplifying that multiplication:
.
On your calculator, raise e to the .44 power to get
A = 190(1.552707219) and
A = $295.01
Let X be the variable used to represent the expression of the total number of books that Mario has read.
We used 4X to represent "four times the number of books". Then we add -2 to interpret the words "for two less than".
Therefore, we have an expression of 4X-2 for the total number of books that Mario has read.
The answer is 26.
This is because, since y is equal to 8, you would put 8 in replacement of y, which is called substituting. It would look something like this.
2 + 3y
2+ 3(8)
2+ 24
26
