the regular price of $63.60.
What is the difference between the
sales prices of the two stores?
DONT ANSWER IF U DONT KNOW.!

Answers

Answer:

6.8

Step-by-step explanation:

30% of 82.40 = 24.72

20% of 63.60 = 12.72

--------------------------------

82.40 - 24.72 = 57.68

63.60 - 12.72 = 50.88

57.68 - 50.88 = 6.8

Find the equation of each line in slope intercept form , the slope is 5 and it goes through the point (2-1)

Answers

y - -5 = (5/2)(x - 3)

y + 5 = (5/2)x - 15/2

y = (5/2)x - 15/2 - 5

y = (5/2)x - 15/2 - 10/2

y = (5/2)x - 25/2

Answer:

y = 5x - 9

Step-by-step explanation:

point-slope equation:

y - y1 = m(x - x1)

y + 1 = 5(x - 2)

y + 1 = 5x - 10

- 1 - 1

y = 5x - 9

On his way to the office each workday (Monday through Friday), Darrell walks by a charitable foundation with a donation bucket set out front. He has decided that he nts to try to be more charitable, so starting next week, he plans to put $1 in donation bucket every day he walks by. He has also estimated that he has already donated $23 to the foundation, Part if x represents the number of weeks thłt Darrell has been making a donation, write a recursive function to represent the total amount he has donated Explain your work

Answers

Answerer: Darrell has already donated $23 to the foundation, so f (0) =$23.

Because x represents the number of weeks, and Darrell is contributing $1 every day, Monday through Friday, he will contribute a total of $5 per week. So, the total amount donated will increase by $5 each week. Therefore, the recursive function will be f (x) =f(x - 1) + $5, where f ($23).
