1. About how much would it cost to buy 18 MP3 players?
2 answers:
Answer: The cost would be $1782 and $3582 respectively.
Step-by-step explanation:
Since we have given that
Number of MP3 players = 18
Number of CD/MP3 = 18
Cost of each MP3 = $99.00
Cost of each CD/MP3 = $199.00
So, the Cost of 18 MP3 would be
And, the cost of 18 CD/MP3 would be
Hence, the cost would be $1782 and $3582 respectively.

Answer:
Step-by-step explanation:
Given:
Two points are given
x = number of minutes
y = length of the lin
⇒ (0, 6)
⇒ (20, 17)
We need to find the equation that represents the relationship between x, y.
Solution:
Using slope formula to find the slope of the equation of the line.
Substitute = (0, 6) and
= (20, 17) in above equation.
So, slope of the line
Using point slope formula.
------------(1)
Where, m = slope of the line
Substitute ⇒ (0, 6) and
in equation 1.
Add 6 both side of the equation.
Therefore, the equation that represents the relationship between x and y is written as:
We have been given that there are 125 people and three door prizes.
In the first part we need to figure out how many ways can three door prizes of $50 each be distributed?
Since there are total 125 people and there are three identical door prices, therefore, we need to use combinations for this part.
Hence, the required number of ways are:
In the next part, we need to figure out how many ways can door prizes of $5,000, $500 and $50 be distributed?
Since we have total 125 people and there are three prices of different values, therefore, the required number of ways can be figured out by using permutations.
