A coat regularly sells for $59.00. It is on sale for 20% off. What is the sale price of the coat?

Answers

Original price : $59.00 ( 100 % )
100 % - 20 % = 80%.

100 % - $59.00
1 % - $59.00 / 100 = $0.59
80 % - $0.59 x 80 = $47.20

Hence, the sale price of the coat is $47.20.

Hope this helps you! :)

F(x)=(3x-1)/(2) find f^(-1)(2)

Answers

Answer:

$f^(-1) (2)=(5)/(3)$

Step-by-step explanation:

To find the inverse of a function, we must replace y for x and then solve for y.

$y=(3x-1)/(2) \nx=(3y-1)/(2) \n2x=3y-1\n3y=2x+1\ny=(2x+1)/(3) \nf^(-1) (x)=(2x+1)/(3)$

Now we can substitute x=2 into our inverse function

$f^(-1) (2)=(2(2)+1)/(3) \nf^(-1) (2)=(5)/(3)$

erica earned 30,000 bonus points on her computer assignment this is ten times as many points as she earned last week how many bonus points did erica earn last week

Answers

if last week she made x points, and this week she made 30, 000
then 30 000 = 10x (solve for x)
30 000/10 = x
so she made 3000 points last week

Final answer:

Erica earned 30,000 bonus points this week which is ten times more than she earned last week. Therefore, she must have earned 3,000 bonus points last week.

Explanation:

The question tells us that Erica earned 30,000 bonus points this week and that this is ten times as many points as she earned last week. In terms of mathematics, this forms an equation where the number of bonus points Erica earned last week multiplied by ten equals the points she earned this week. You can figure out how many points Erica made last week by dividing 30,000 by 10. So, Erica earned 3,000 bonus points last week.
