Answer:

Step-by-step explanation:
Given
Straight Line, PS
Such that


Required
Find PS
From the attachment above, it can be seen that RS is a continuation of PS;
This implies that

Substitute
and 

Collect like terms


Hence, the length of PS is 
If you would like to know what was the percent decrease in price, you can calculate this using the following steps:
x% of $299.99 is $180.55
x% * 299.99 = 180.55
x/100 * 299.99 = 180.55
x = 180.55 * 100 / 299.99
x = 60.19%
100% - 60.19% = 39.81%
The correct result would be 39.81%.
Answer: Our required model is 
Step-by-step explanation:
Since we have given that
Number of toys = 1,250,00
Every year is expected to increase by about 150% pr year.
So, initial value = 1250,000
Rate of change = 150%
Let the number of time = t years.
So, we will use "Compound interest":

Hence, our required model is 
We need to find the quotient of the given division problem.

In order to find its quotient, we will use long division.
)
First of all, we put x in the quotient as
goes into
, x times.
So, we get:
)
(x

Upon subtracting, we get:

We can see that
goes into
, -2 times, therefore, the next term in the quotient will be -2. This makes our quotient as (x-2).
