If the price starts at $25,000 and decreases by 15% each year, that means it is 85% of the value it was the previous year (100% - 15% = 85%). We write this out as an exponential function using the equation P(t)=p(r)^t where P(t) is the price function during time t, p is the original price, and r is the 85% we found. Plugging this in we get P(7)=25000(0.85)^7 which is about $8014, rounded to $8000. Therefore A is correct.

A line passes through the points (3,21) and (8,26) Write a linear function rule in terms of x and y for this line.
Answers
Answer:
y = x+18
Step-by-step explanation:
I'm not too sure about the terminology but I hope this helps!
In order to find the equation of any line, one can use the equation
m (gradient) = (y1 – y2 ) ÷ (x1 – x2)(3,21) is the first named point; therefore, 3=x1 and 21=y1
Following the same logic, for the second point, 8=x2 and 26=y2.
Next, substitute these values into the equation above:
m = (21-26)÷(3-8)
m = -5/-5 = 1
Therefore, the gradient of this line is 1. So far our y=mx+c line equation has this information:
y=1x+c
Plugging in x and y values gives the y intercept (c):
21=3+c (the values from point (8,26) can also be used here)
c = 18
Therefore, the line equation is y = x + 18
As a function, this could be f(x) = x + 18 (although I'm not too sure about this part!)
I hope this helped.

В.
=C
5
C. ($9.98 + $24.99 + x)5 = C
D. 5+ ($9.98 - $24.99 + x) = C
Answers
Elena's total cost (C) is 5(9.98 + 24.99 + x)
Since each dog leashes cost $9.98, each bag of dog food cost $24.99 and each crate of egg cost $x, hence:
Total cost (C) = 5 * $9.98 + (5 * 24.99) + (5 * x)
C = 5(9.98 + 24.99 + x)
Therefore Elena's total cost (C) is 5(9.98 + 24.99 + x)

The difference between two whole numbers is 8. Twice the smaller number is 4 more than the larger number.
What is the smaller number?
Enter your answer in the box.
smaller number =
Answers
Step-by-step explanation:
the numbers : x, y
x - y = 8
2y = x + 4
2y - 4 = x
we use the last equation in the first :
2y - 4 - y = 8
y - 4 = 8
y = 12
x = 2y - 4 = 2×12 - 4 = 24 - 4 = 20
the smaller number is 12.
The value of the smaller number will be 12.
What is an expression?
Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The difference between two whole numbers is 8.
And, Twice the smaller number is 4 more than the larger number.
Now,
Let two numbers are x and y.
Where, x is larger number and y is smaller number.
Since, The difference between two whole numbers is 8.
Hence, We get;
⇒ x - y = 8
⇒ x = 8 + y ..(i)
And, Twice the smaller number is 4 more than the larger number.
So, We get;
⇒ 2y = 4 + x ..(ii)
Substitute the value of x from (i) in above equation, we get;
⇒ 2y = 4 + 8 + y
Solve for y as;
⇒ 2y - y = 12
⇒ y = 12
Thus, The value of the smaller number will be 12.

A quick survey of peanut butter prices had standard deviation and mean of $0.26 and $3.68, respectively. Compute the area for a peanut butter jar costing more than $4.25.
Answers
The area for a peanut butter jar costing more than $4.25 is 0.0143.
Z score is used to determine by how many standard deviations the raw score is above or below the mean, The z score is given by:
[tex]z=\frac{x-\mu}{\sigma} \\\\where\ x= raw\ score, \mu=mean, \sigma=standard\ deviation[/tex]
Given that μ = 3.68, σ = 0.26
For x > 4.25:
[tex]z=\frac{4.25-3.68}{0.26} =2.19[/tex]
From the normal distribution table, P(z > 2.19) = 1 - P(z < 2.19) = 1 - 0.9857 = 0.0143 = 1.43%
The area for a peanut butter jar costing more than $4.25 is 0.0143.
