It will have 2 solutions! this is because a negative and a negative cancel each other out and will make a positive under the radical.
The amount Howie will pay back at the end of one year is $26000.00
The given parameters are:
-- the principal amount
-- the interest rate
--- the duration
The amount to pay back in this duration is then calculated using:

So, we have:


Express percentage as decimal


Multiply

Hence, the amount to pay back is $26000.00

I am unable to solve this problem.
Answer:
(a)23 (b)90 (c)3
Step-by-step explanation:
The equation for the line of best fit for this situation is given as
where x=average temperature in degrees
y=average number of hot dogs she sold,
(a) The expected number of hot dogs sold when the temperature is 50° would be___hot dogs.
When x=50°

When the temperature is 50°, the expected number of hot dogs sold would be 23.
(b)If the vendor sold 35 hot dogs, the temperature is expected to be ___degrees.
If y=35

Multiply both sides by 10/3

If the vendor sold 35 hot dogs, the temperature is expected to be 90 degrees.
(c) Based on the line of best fit, for every 10-degree increase in temperature, she should sell 3 more hot dogs.
The solution for s in the given equation is 
The question seems to be incomplete
Here is the complete question:
Solve for s in this equation
Depreciation.
To solve for s, that means we should make s the subject of the equation
From the given equation,
To solve for s, first multiply both sides by n to clear the fraction
We get

Then,

Now, add s to both sides


Then, subtract nD from both sides

∴ 
Hence, the solution for s in the given equation is
