The amount of money that he should have at the closing of December should be $227.69.
The correct answer choice is option C
How to find total savings?Given that,
Starting amount = $24And, it plans to save 10% more as compared to the last month.
The amount of money that he should have at the closing of December can be solved using the concept of geometric sequence.
First term, a = $24
Common ratio, r = 1.10
Number of terms, n = 7
So,
Sn = a1×(r^n -1)/(r -1)
S7 = 24×(1.10^7 -1)/(1.10 -1)
= (24×0.948717) / 0.10
= $227.69
The total amount Cory will have saved by the end of December is approximately $227.69

Answer:
(c) $227.69
Step-by-step explanation:
The amounts Cory will be adding to his account comprise a geometric series with first term $24 and each successive term 10% more, or 1.10 times the previous term. The total amount Cory will have saved by the end of December is the sum of 7 terms of the series.
__
sum of geometric seriesThe sum of ...
24 +1.10×24 +1.10²×24 +... +1.10⁶×24
is given by the formula ...
Sn = a1×(r^n -1)/(r -1)
where a1 is the first term (24), and r is the common ratio (1.10).
formula applicationFor the series representing Cory's deposits, we have ...
S7 = 24×(1.10^7 -1)/(1.10 -1) = 24×0.948717/0.10 ≈ 227.69
At the end of December, Cory will have about $227.69.

Equation in point slope form:
[tex]\sf\rightarrow y - 3 = -4(x - (-4))[/tex]
[tex]\sf\rightarrow y - 3 =-4(x + 4)[/tex]
Additional, in slope intercept form:
[tex]\sf\rightarrow y = mx + b \quad where \ 'm \ is \ slope' \ and \ 'b \ is \ y-intercept'[/tex]
[tex]\sf\rightarrow y = -4 x - 16 +3[/tex]
[tex]\sf\rightarrow y = -4x -13[/tex]
Expand and simplify: (-7y - 8) (y - 4)
To expand an expression, use FOIL method.
F - FirstMultiply the first term in each expression inside the parentheses.-7y and y are the first terms in each expression.
(-7y)(y) = -7y²
O - Outside Next is to multiply the terms outside. (The first term in the first expression and the last term in the second expression)-7y is the first term in the first expression

Let the rational function [tex]f(x)= \dfrac{mx^a}{nx^b}[/tex] where and a and b are degree of numerator and denominator.
If a < b , then the y axis y = 0 is a horizontal asymptote.
If b = a then horizontal asymptote is the line y = p/q
Here the value is b = 2 and a = 2
Since b = a the horizontal asymptote is the line

You play a game that requires rolling a six-sided die and then randomly choosing a colored card from a deck containing 3 red cards, 6 blue cards, and 8 yellow cards. Find the probability that you will roll a 5 on the die and then choose a red card.
The probability of getting a red card and rolling a 5 is = 3/85
How to find the probability?First, we want to find the probability of rolling a 5.
There are 6 outcomes on the six-sided die, so the probability of getting a particular value is:
P = 1/5.
Then, the probability of randomly drawing a red card is given by the quotient between the number of red cards and the total number of cards:
P' = 3/(3 + 6 + 8) = 3/17
The joint probability is given by the product between the individual probabilities:
